  1. Very interesting...I just found this radio for sale on eBay. It's a NIB Hitachi KMS-2411Z. Note that the box is labeled "280Z Coupe" and the part number is one digit off from the part number listed on my box (99993-00137 vs 99993-00147)...so, here's what we have: KMS-2411Z......280Z Coupe....99993-00137....Original factory radio installed in the 78Z (and possibly/likely the 77Z) KMS-2511Z.....280ZX Coupe..99993-00147...Unknown application/year model Visually, the two radios appear to be identical...and we are not aware of any models of the ZX that utilized this style of radio.
  2. I think we're saying that it's possible (maybe even likely?) that the original Datsun box is labeled wrong. However, it still doesn't answer the question of what year model(s) Z/ZX's the Hitachi KMS-2511Z radio was installed in. I'm fairly certain that the KMS-2411Z radio was installed in the 77 and 78 year model Zs. And it seems likely that a radio model numbered 2511Z would be an update/followon to the 2411Z model number. I guess I was hoping that a forum member might have some first hand experience with the 2511Z model radio.
  3. Thanks siteunseen...i did see that post, but i think the original poster is incorrect in saying that the KMS-2511z is original equipment for the 73-76 Z cars. To my knowledge, none of those year models came with stereo radios from the factory. And I agree...it seems that the ZX radio set up did include cassette players. I'm sure you'd agree that it is curious that the box states "280ZX Coupe"
  4. Please see attached photos....Many years ago I purchased this NIB radio to eventually install in my 78Z. At the time I purchased it, I thought that it was the original factory radio for a 78Z. I came to this conclusion by simply observing that, visually, it was identical to the original radio that came with my 78Z. My original equipment radio works, sorta, but has "issues". However, recently, I noticed that box label on this replacement radio states "KMS-2511Z" and "280ZX Coupe". The original radio is labeled "KMS-2411Z". I found this curious mainly because my understanding was that the radios in the ZX models beginning in 79 had a completely different (new? updated?) radio system installed. In other words, I didn't think that this style of radio was installed in any of the ZX models. So my question is...what is the difference between this NIB radio (KMS-2511Z) and my original radio (KMS-2411Z)? Is there any reason to believe that this radio won't work perfectly in my 78Z? An internet search didn't come up with any useful information on the KMS-2511Z radio. Thanks!
  5. Thanks for that thread reference...I really enjoyed reading through it. I considered the possibility that my bracket, as shown in the photos above, was mounted backwards onto the antenna assembly. However, check the photo I've included here...there are 2 holes on the bottom of the bracket...one for a screw, and one for the drain tube. The hole for the drain tube includes 2 tabs that clamp the rubber hose into place. So I don't think there is another way that this bracket can be oriented and still have those 2 holes function as intended.
  6. Thanks for that information! I'll pass it along to my buyer. To me it's all about getting him an antenna that will work in his car.
  7. Thank you...that would be very helpful.
  8. I have a fully functional factory original antenna that I''m offering for sell to a fellow Z owner. His car is a 78Z. The problem/question I have is that I don't know what year model my antenna come out of. There are very few distinguishing markings on the exterior of the antenna...only a few numbers. We have concerns that different year model antennas mounted to the car body in different ways, using different brackets. I'll post 3 pictures...2 of my antenna, and one from my 78Z FSM. It definitely seems from these photos that my antenna is not a 78 model, based on the bracket design. I'm just looking for opinions on which year Z my antenna came from...and what it would take to mount it in a 78Z. Thanks!
  9. Ok..thanks for clarifying that. I do see what you mean. I just guess that interpreting wiring diagrams is not one of my strengths. Lots of good info you (and others) have posted in this thread.
  10. So White is right side speaker out and Black/Red is left side speaker out. Thats interesting. And it would make sense I guess that each speaker would need its own wire driving it for a stereo system. However, that setup doesn't match the FSM wiring diagram description. The 78 FSM wiring diagram shows both speakers being driven by the Black/Red bullet connector wire. In fact, it doesn't even show the White wire. I'm guessing this is another example of a diagram not being updated to reflect system upgrades from the original configuration.
  11. Thanks for that...I see your point....at least now, with the photos I posted in this thread, forum members can clearly see the wire scheme/colors on the two connectors on the radio-side of the sub harness (I've also heard it referred to as a radio pigtail harness). Too bad I still couldn't figure out what the function of each of these colored wires is...
  12. Thanks for the compliment...I also saw that same schematic in my FSM....but I was somewhat confused since the schematic didn't exactly match the actual configuration in my car...and I know my car hasn't been altered from original...so I thought it would just be more useful if I posted what was in the car. Specifically, notice how that schematic shows the connections at the radio as a 6 + 2 plugin vs. the 5 + 3 config. in my car. I'm not sure why the difference....maybe the clarion radio setup was different? Anyway, hope all this helps...good luck!!
  13. And just so there's no confusion over which radio connections we're discussing here....here's a pic of the front side of the radio...Hitachi KMS-2411Z
  14. And here's the car-side connections of the radio sub harness. According to my FSM the speakers are the wires that are Black & Black w/ Red stripe....although I haven't tried to confirm this in my car
  15. Here's a photo that shows specifically which color wires connect to each of the "spades" in the back of the radio. Note that on the 6 pin connector that the lower right position is unused...at least in the hitachi radio in the 78 year model Z. So there are 8 wires that connect into the radio. The other end of the "sub harness" has the wires grouped together differently...I'll post a photo of that end of the sub harness below...
