Too much hyperbole in the ad. I couldn't even read all of it before throwing up in my mouth a little. I did look at the pictures, though. It looks nice, but I'm betting on no bids.

Some people have sent off their dashes to be recovered, but IIRC it was with mixed results. Interior Auto Restoration - Dash Board Restorations | Dash Restoration | Cracked Dash Here's another: Welcome To Just Dashes

Sadly, a young man who was a member of Z Atlanta passed away recently when he had an accident in his 350Z. His car was much more modern than my Z cars, but the safety features weren't able to prevent his untimely demise. The risk is there pretty much no matter what kind of car you drive. As stated in other posts, how you drive is going to be a major contributor. When I am driving my Zs, I fully realize that I must manage the risk as much as possible via careful driving and alertness to vehicle condition in order to increase the chances of me getting home safely. Convince her that you going to a Skip Barber driving course would improve your safety on the road. I'm sure you could Google up some statistics demonstrating the benefits of such training.

Actually, IMHO, Wade was not far off the mark. The OP stated in his initial post that he didn't understand much of what he was doing and that he was looking for a shortcut. I try to minimize jury-rigging wiring in the car. The modifications I make tend to be things like adding relays to the headlight circuit or bypassing the obnoxious seatbelt interlock relay. I wasn't going to offer any advice myself, but when the OP asked about an engine harness, I directed him to a potential & reputable source. I will try to help people with electrical issues online and on the phone. However, I would agree with Wade that if you have little knowledge of automotive electrical systems and want to ignore all of the work the Nissan engineers did during the design & production of the car, it would be best to seek the services of a professional.

Did you try Zcarsource?

One of the functions of the AFM is to cut power to the coil on the fuel pump relay when the engine isn't running. If you replace the AFM, what are you going to do to compensate for that signal?

Jim Frederick's chop-top 240Z was featured on NPoCP at Jalopnik today: For $15,000, This Fairlady Will Let You Take Her Top Off So far, Crack Pipe is winning the vote.

Why not just use the wiring diagram from the service manual itself? XenonS30

If I can find it (and have time and can remember to look), I have the added wiring harness that was used for the electric fuel pump. I can take a picture of it so you can see if you have one in your engine bay.

That is for an early Z. There are differences between that one and the wiring for a 73.

See, all I had to do was mention BGM and he appears. He is mystical. He is...Black Gold.

Does your 73 have the Nissan factory-designed electric fuel pump retrofit? That could account for some of the wiring differences you are finding.

Did you point the Diode the right way? If not, the alternator won't see the battery voltage.

Contact Black Gold Man. While he's a ZX kind of guy, think about looking at your engagement pictures and seeing... Black Gold

The wire is melting due to too much current. With no pictures, meter readings etc., it is difficult to diagnose the problem. It would not be due to the wires going from the battery to the starter. What is your ammeter reading when you're driving the car? How old is the battery? Maybe you should try the plug that MSA offers: Motorsport! Alternator Upgrade Adaptor, 70-73 240Z - The Z Store!

Yes, 40 year old wires can be fragile. For the parking light circuit, you can reduce the current loading by switching bulbs over to LEDs. Here is a thread with more information: http://www.classiczcars.com/forums/electrical-s30/40600-sold-leds.html

The entire switch can be purchased. Beck Arnley 201-1179 Key, Lock And Ignition Switch Assembly : Amazon.com : Automotive Something tells me that there is something worn in the body of the switch that allows the key to move the switch too far.

When you say you replaced the switch, did you replace the entire assembly or just the back part?
