It’s a full system, so part numbers include the header. I found three: 15413 15415 15418

RTV seems to do the trick. unrelated… Does anyone know of a build thread with really good pictures of the original copper 280z air conditioning lines and hoses? I want to see how those were routed and where they went through the firewall so I can approximate that with my setup. I haven’t been able to find a diagram that show the actual routing.

Doesn’t look like Streeter Corp can help with the details, although I will probably still order through them. Here’s what they said about my questions: As we operate wholesale with the manufacturers we can't really be digging into deep info about particulars, that's not the kind of retail service we provide to you or them to us. These were my questions: 1. I can tell the EPU is a full system, but I can’t tell if the header is the same as the Super Ex or if it has also been updated. 2. I see that the EPU version can accommodate an r200 differential, but does it still work with a r180 and the factory cross member that has indents for a twin pipe exhaust? 3. I saw one website saying the EPU version has an O2 sensor, but I wasn’t sure where it is. Is it on the header or the y-pipe? 4a. Is the EPU system a bolt in setup in a left hand drive car, or is there going to be a clearance issue with the steering shaft hitting the header? 4b. Related to this, are all of the hanger brackets welded on already? 5. Are there any other changes to the EPU over the Legalis r / super ex that explain the price increase over the older setup?

I know this thread is old… and, um, tense… but it’s also the best resource for info on the Fujitsubo 240z systems on the internet… if you dig through it. So I’m posting an update in case people weren’t aware: Fujitsubo have a new new version of the Legalis R on the market. It is the EXH Performance EPU version (15-15415) and from what I can tell it’s updates are an O2 sensor and rerouting the pipes at the rear of the car to split before and wrap around the dif. So that make three versions you can buy online right now: The original with the fatter resonator: The updated one with tucked up adjacent pipes: And this one with the split: It also looks like it only comes as a total system packaged with the Super Ex header. There are many things I’m not clear on, though. The split in the pipes accommodates an r200, but does that mean it doesn’t align with the depressions for the twin pipes on a stock r180 differential mount? We’re there changes made to the Super Ex that helped achieve their supposed performance gains (this is supposed to improve performance over the 2nd version)? Does everything fit nicely on a LHD car, as compared to either of the previous versions)? I reached out to Fujitsubo via Instagram for details but doubt I will hear anything. The retailers can’t answer these questions either.

I've started to redraw my wiring diagram. To give you an idea of how I am changing it from what we have on the site now, here's the fuse box from the original followed by the one I redrew. I wish I could say this will be useful for everyone, but I will be deleting and adding a bunch of components, so it's utility for other people will be limited. Diagram: Sample:

I plan to use LEDs but I want to wire the car so that I don’t HAVE to use LEDs, particularly for the headlights. My thoughts on having 14 AWG be my smallest wire was coming from a few things: First, the amount of fried wiring I found. It’s possible the heat came from outside but in places like under the dash I don’t know what would cause that, so I was assuming that it was overload on the wiring. Second, the general use of 10-amp fuses for everything that wasn’t one of the fatter wires, plus the gauge charts I’ve been using. However, I suspect the dash maybe could come down a notch for all the instruments and save me some headaches with fitting all that stuff in there. Third, just eyeballing stuff looks like a lot of 14 AWG. Maybe I’m off base and It's smaller than that. Tough to tell since it's actually Japanese (square millimeter?) wire and not AWG. need to go back over it more carefully. I would love to plug all the numbers for everything in the car into a calculator, but I just don’t know where to find that information.

I did a quick tally of which wires need to be which gauge and this is what I ended up with: Components Gauge Wire Color Starter Ground, Combination Switch 10 Black Black w/ White Fuel Pump Green Headlights Red w/ White Starter, Ammeter White Alternator, Ammeter White w/ Red 12 Black w/ White Ignition Switch Black w/ Yellow Ignition Switch Green w/ White Headlights, Combination Switch Red Rear Glass Defroster Red w/ Black Light & Horn Switch Red w/ White Headlights Red w/ Yellow Fuse Box White Ignition Switch, Combination Switch White w/ Red All others would be 14 AWG. There may be some 16 or 18 AWG in the car originally, but I don't see a reason to go that light. Please let me know if you think I have any errors here. I'm also wondering if it would be worthwhile to step everything up one level, or if that would be a waste of money and weight.

Question about the black goop inside the frames for my rear quarter panels: what is it? I was thinking RTV or body caulk. It doesn’t seem like it’s weatherstrip adhesive. I want to be able to replicate this after I clean all my parts up.

I received the last of the parts I ordered for the 5-speed overhaul on Sunday this past weekend, so three weeks total wait time. Not bad considering one of the bearings was lost in transit to Courtesy Parts and had to be ordered again. Not as fast as ordering a quest kit, but I went above and beyond what's available in those, plus it's all OEM.

Side Project: I was able to find Nissan OEM versions of everything I need to overhaul the five speed. Luckily, I don’t need synchros, although you can still get them OEM from Courtesy Parts and the handful of Nissan dealers I called. I had to use a handful of places to get all of these, and I’m not 100% certain two of these are OEM despite reassurances from the retailer, but it wasn’t difficult to get it all in hand. Maybe 30 minutes on Google. I dropped these off at the transmission shop yesterday. I have no idea how long it is going to take for him to get it done, but I’m hoping to have it back by the end of September. Here's my parts list: - 1x Main Input Shaft Bearing (PN 32273-N4800) - 1x Main Input Shaft Bearing, Adapter Plate (PN 32273-36900) - 1x Main Input Shaft Bearing, Extension Housing (PN 32203-14360) - 1x Pilot Bearing, Input / Output Shafts (PN 32272-36910) - 3x Needle Bearing, Main Shaft Gears (PN 32264-14601) - 1x Counter Shaft Bearing, Front (PN 32219-E9020) - 1x Counter Shaft Bearing, Adapter (PN 32203-E9800) - 1x Counter Shaft Bearing, Rear (PN 32319-N4870) - 1x Reverse Idler Gear Bearing (PN 32272-36910) - 1x Front Cover Gasket (PN 32112-08U01) - 1x Oil Gutter (PN 32137-E9000) - 1x Front Seal (PN 32114-Y4000) - 1x Rear Extension Seal (PN 32136-U010A) - 3x Checking Spring (32830-20100)

My kids dinged the front left fender the other day with the door from our Subaru, so I am trying to embrace the concept of Wabi-sabi. The goal here is a Z built from the “best” parts that will go on it, or, a Z that’s what Nissan could have made if they went all out in the beginning. Trying to keep the newer tech / styles to a minimum. But yeah, I’m getting itchy.

Some updates: Fresh air intakes ZX AC Bracket ZX AC Bracket after sandblasting and paint That same ‘78 280z rear glass with an OEM rear window seal to fix this gaps in the corners. This was a major PITA to install. Super tight. I also noticed a scuff in the shape of a Z logo. I think there was a sticker or paint on the glass and they didn’t take care getting it off. Gonna have to polish guy. Inner and outer (1970 version) weather strips

Table Number 4! This table represents the other half of the dashboard harness for a 1973 240z (PN 24013-M3322). It was much easier than the other half. There only two items I couldn't figure out: a missing wire in the blue 10-pin connector to the engine harnes and a blue wire near the fuse box branch what might be power to the Radio (pink cells). Pretty close to done with this inventory now. I have some small harnesses to capture still (fuel pump harnesses and the heater controls harness), but I don't think I need them for my final build so I may do that later. 1973 240z Dashboard Harness (24013-M3322) Inventory Position Component Connector Color Connector Style Connector Image Direction # of Pins # of Wires Diagram Wire Color Sample Wire Color Min.

Amazing! So not only does that solve #7 in harness #1, it solves for position #5 in harness #2, which you would not know because I have not posted the table for yet. The only mysteries I will have left are the 4 wires that are missing (2 from the dash and 2 from the engine) and a blue connector on this harness I am chasing now, which might be to the radio lights. Maybe I can find those using the diagrams.

Here you go. It's the one in the black sheath with a female bullet connector pointing to the top of the photo (between the blue wires and the white wire w/ the red stripe).

Oh man, this is so helpful! Thank you. I keep forgetting about the speakers. I'll make these updates in my previous post. The position of the blue with red stripe wire at position #7 is right out the big colored connectors. It is spliced to a blue / red wire that goes to the fuse box and another one of the same color for the junction connector that comes out at the ignition switch. It has something to do with the wipers. The wiring diagram shows 3 blue w/ red wires: one going from the ignition switch to the fuse box, one out of the fuse box to the wiper motor, and one from the combination switch and connecting to a yellow / white wire that goes to the wiper fluid bottle.

Oh, I should add that I tried just having strips of dynamat, but it showed through the headliner. If you’re going to use any you have to cover the entire roof, and you have to get it on as smooth as possible. The headliner is surprisingly bad at hiding bumps and ridges under it, despite the thick foam backing.

I have a couple of updates: 1. The first half of the dash harness inventory is up in my wiring build thread. Now that that’s in the bag I’m moving on to the second half of the dash harness. 2. I’ve been trying to sneak in small things to help me feel like I’m making progress. This week’s small thing was the head liner. IMG_4916.MOV IMG_4934.MOV Nice and quiet!

Table Number 3! This table represents half of the dashboard harness for a 1973 240z (PN 24013-M3321). It's… okay. There are three items and a missing wire I can't identify (pink cells) and I am unsure about what I marked as the heater (bright yellow cells), but it's close. The other half will be in the next table.

Yeah, these are the threads that informed my previous comments. I’m glad you pointed that out, though, so I know the symptom to watch for. I am pretty sure this is a five-speed lever and doesn’t need to be ground for a few reasons, not least of which because it matches the truck lever that came with the transmission.

Time for a side quest: In my continuing saga to clear my basement and get this Lego kit of a car together, I was cleaning the shift lever that came with it. Yes, it was a loose part in a cardboard box when I got it. Not, I didn’t get any info with it. From what I can tell this is a five speed lever. The piece below the pin hole is 37.5 mm from the end of the ball to the crease where the lever becomes sort of spherical: It’s identical to the long lever that came in my transmission, which is a five speed out of a truck. I think I’m good to go, but if anyone sees a red flag here, let me know. This week has had a string of happy accidents, and the PO’s good up here worked out for me if my research is correct.

Okay, this one is going to be a long one, so I will try to bust it up into pieces to keep the conversation organized, because the dash harness (or harnesses, as it turns out) was a doozy. In one way it wasn't as tricky as the engine, because it is the correct harness for the car this time, but it was trickier in another way in that there were few things I could identify before I disconnected them (being disconnected when I bought the car) and the ones with spade and bullet connectors are not in the FSM Body Electrical section, so I am juggling between several years of FSM, the diagrams I downloaded here, and lots of Google searches. For the purpose of clear communication I will refer to both of these harnesses as halves of the larger "dash harness." If I need to distinguish between them I will refer to the one with all of the lightbulbs as harness #2 and the other one as harness #1, since their part numbers are 24013-M3322 and 24013-M3321, respectively. --- @SteveJ, @zKars, @Zed Head, and everyone else, I am hoping to enlist your help in identifying at least some of the things I couldn't figure out so I can fill in the blanks in the table. Hopefully some of you will know what these should be. Condenders are the 4-way flasher, heater, air conditioning power, resistor, fog light switch, and wiper motor. Missing Wires: In capturing the wire mapping from the FSM, I found that my harness is missing a black wire with a yellow stripe from the blue connector, and a black wire from the green connector (not the heavier gauge wire that goes to the combination switch). After reviewing the FSM and the diagram, the only black and yellow wire running through the dashboard I see is the one from the ignition to the starter (via the inhibitor switch in automatic cars). I have accounted for that one and it is in a different connector. The black one could be anything, really. I don't have any black wires missing on the other ends that I can tell. Unidentified Connectors #1 & 2: There are several places there the two harnesses connect to each other via bullet connectors. I have figured out what almost all of the bullet connector are throughout the whole harness except for a few on each half. OF the first two, one is a male bullet on the end of a 3-inch blue wire with a red stripe exiting Intermittent Relay plug. The other one is a female bullet also on a blue wire with a red stripe going to the fuse box. #3 (Harness 1): Next is a 3-pin connector with 3 wires (White w/ Black, White, Blue) on the branch that goes down the center console to the fuse box. The blue wire has a blue sleeve on it that may or may not be a repair from the previous owner. This one is right next to the connector for the antenna motor (left side of the photo above), so I thought this might be for the radio, but I have that one accounted for. There is no component on the wiring diagram with this combination of wire colors, as far as I can tell. #4 (Harness 1): This one might be power for the Air Conditioning, or it could be for the heater. There is a blue wire branching off the 30-amp fuse in the diagram for that. The trouble is, that fuse should have a red wire coming off it for the blower fan, but I am not seeing that in this mess. I think this one is for the heater. #5 (Harness 1): Another truly perplexing one is this 3-prong clip with two black and one green wire. This exits the center-console branch along with the ones above, but it's about a foot long. No idea what this is. it's missing in the FSM and the diagram, and I don't see a component with this color combination. I think this one is for the buzzer. #6 (Harness 1): There is a blue wire with a white stripe right next to the connectors for the fuse box. I think maybe this one is for the four-way flasher, but I am not certain. This is for the fuse box. #7 (Harness 1): This 2-prong connector is down the console near the choke and seat belt lights. Wires are black with a white stripe and green. #8 (Harness 2): Again, on the branch going down to the fuse box, this time on the other half, there is a blue wire with a female bullet connector. Maybe this connects to the other stray blue with I thought was for the AC, or maybe this is for the heater. I have a feeling these two are for those two components, it's just a question of which is which. I think this one is for the AC. #9 & 10 (Harness 2): These last two are also on the fuse-box branch. One is a thicker white wire with a sheath and a female bullet connector (middle wire in the photo below), which should make it easy to identify, but I'm still confused. This one splices to the fat wire that goes from the engine harness to the Ammeter. This is also for the fuse box. The last thing I can't figure out is the 2-prong connector is the photo above. It is not in the FSM and I can't find a component in the diagram with this combination. Maybe it goes to the resistor, because I do have an unaccounted for black & white wire that I mentioned earlier on the other fuse-box branch, but they are both paired with other wires (green / red) that are not showing in the diagram for that component, so I don't think so. Anyway, that's what I have to figure out before I can wrap up this inventory. One thing all the Googling I've been doing is teaching me is there are a bunch of little harnesses I might be missing. I already know about the tail light, fuel pump, headlight, turn signal, and step light harnesses, but I just saw a center console harness I haven't seen before on eBay (may be for a 280z ¯\_(ツ)_/¯ ). After this one I'll do the fuel pump harnesses and research the others. Then I can move on to deciding which materials to buy to make the new one. Thanks in advance for any help.

Thanks for the advice guys! I’ve been talking to Vintage Connections about their 240z kit, which they claim contains all the connectors I’ll need for the car. I think I am going to get it if it is accurate to my inventory. I’ll report on that later. For the 10-pin clips, I may reuse the one I have, but I’m going to see if I can figure out an alternative before I decide. @zKars I was going to try to reuse these, but after I stripped the wrapping off I found so many bad splices, burnt through wires, corrosion/oxidation, cut wires, and other issues I decided to rebuild from scratch. Plus, the engine harness isn’t even the right one, being for an automatic, and I have numerous components to add or remove. I honestly think it’s going to be less work to make fresh harnesses.

I'm deep in the process of cataloging the dashboard harness and it's making me lean toward trying to use OEM connectors, rather than modernizing the harnesses with new technology (although I am open to hearing arguments against this). The one place I think this is going to be super challenging is with the big 10-pin connectors that come in blue, green, white, and black and join the individual harnesses together. Does anyone have an idea of whether or not these can be found new or NOS anywhere? I haven't seen them anywhere, whereas I have been able to find pretty much all of the other connectors used in these harnesses somewhere.

Okay. Noted. I will include these details including the loop mod in the tach in my overall wiring plan. I’m not going to be able to test this stuff until I have it all in one place, unfortunately, but at least I have it all captured here for reference. Thanks guys!
