Mycarispurty Posted May 8, 2007 Share Posted May 8, 2007 I have a 76 chassis wiring harness (or maybe a 75, can't recall) and I'm curious what are the differences on it and the 77 harness (my car is a 77 5 speed)? Mine has some pretty bad spots where previous owners tried to re-engineer what Nissan did years ago and it didn't turn out so well. I thought about using an EZ Wiring kit but that would require some fancy work getting combo switches and things to work. However, if the other harness I have is good and clean, no screwed up wires or anything, I might just use it and get all the connections good and tight and make sure all my grounds are good and clean and just rewire it. It'd be a lot easier considering all the plugs would be good and wires the right length to lay correctly under the carpet. Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted May 8, 2007 Share Posted May 8, 2007 Which part of the harness exactly are you looking for? I see you said chassis, so just to be clear... I have a brand new oem engine harness for the 75-76, thats why I'm asking, just to be sure. Quote Link to comment Share on other sites More sharing options...
Mycarispurty Posted May 8, 2007 Author Share Posted May 8, 2007 I need the part that runs into the engine bay and into the cabin before it branches off into subharnesses for the dash and rear of the car, and has the fuse panel in it. I say subharnesses because I wouldn't imagine they'd use one whole harness to do all of that, but I could be wrong. I know there are some differences, just not quite sure if it's only in plug styles/shapes, or if other circuits were added to later years, or relays were set up in different ways or whatever.

gvincent Posted May 9, 2007 Share Posted May 9, 2007 I know there are definately differences between my 78 and 76 especially in the FI harness, also part of the front lighting, underhood relay chassis, AC wiring, etc. harness coming through the passenger side firewall. Also the FI fuel pump relays are located in different places if I remember right. Greg Quote Link to comment Share on other sites More sharing options...
Mycarispurty Posted May 9, 2007 Author Share Posted May 9, 2007 Well my FI harness is ok for now, just redoing the chassis. I'm not sure if I'm going to stay stock, go turbo motor, or v8 so I'm not touching the FI one yet. I guess I need to find a good 76 wiring diagram so I can see the colors and sorta match them up with mine. I'm not going to be using A/C, just the bare minimum stuff I have to use. If I can't find a good deal on a 77 harness I guess I can make my 76 one work. Quote Link to comment Share on other sites More sharing options...
jasonZ Posted May 9, 2007 Share Posted May 9, 2007 Hey Matt, I thought you were selling your Z. Glad to see you didn't have to part with it, nice looking car. Jason Quote Link to comment Share on other sites More sharing options...
Mycarispurty Posted May 9, 2007 Author Share Posted May 9, 2007 Thanks. It's hard to decide, I've had ZERO cash offers, and a bunch of trade offers for stuff I'm not interested in. I figure if I sell it, if it has intact wiring then it'll be easier to sell. And if I keep it, much better for me afterwards, becuase of better wiring Quote Link to comment Share on other sites More sharing options...
gvincent Posted May 9, 2007 Share Posted May 9, 2007 I have the 77 and 76 manual in pdf but they are about 45Mb each, I also have 75, 77, and 78 wiring diagrams that can be sent by email if you want them. Classic Zcar has some on their website as well. Greg Quote Link to comment Share on other sites More sharing options...
Mycarispurty Posted May 9, 2007 Author Share Posted May 9, 2007 Ok I'll take them both. Will suck trying to look through it on a computer screen, but it's better than nothing. Mycarispurty@aol.com Quote Link to comment Share on other sites More sharing options...
Mycarispurty Posted May 9, 2007 Author Share Posted May 9, 2007 Oh my bad, it's a 75 harness, 76 FI harness. The seller wrote me a note in the box they came in, so it's a 75 I guess. I guess I'll take your 75 and 77 harnesses if you don't mind. Quote Link to comment Share on other sites More sharing options...
Mycarispurty Posted May 9, 2007 Author Share Posted May 9, 2007 Thanks for the emails Greg. I looked at that 75 harness, even if the wires aren't all mauled and chewed up, I'm not putting that thing in my car. I think I would rather just balls up and get the aftermarket kit and solder everything to the connection it's going to. Great connection with new wires is probably the best way to go.

gvincent Posted May 9, 2007 Share Posted May 9, 2007 I will try and send the files to you but usually aol has an email attachment limit that is pretty small if I remember right. I will send them anyway but aol might bounce them back. Let me know if you get them ok. Greg Quote Link to comment Share on other sites More sharing options...
Mycarispurty Posted May 9, 2007 Author Share Posted May 9, 2007 I got them. I'm definitely going to use an aftermarket, 30 year old parts just won't be trusty enough for me I guess. I just fear having to wire into those combo switches for wipers, lights, turn signals, all that Quote Link to comment Share on other sites More sharing options...
gvincent Posted May 9, 2007 Share Posted May 9, 2007 The biggest difference I can see is with the FI Harness, your other harness may be good to swap, the 77 had more relays where the fuseable links are located but that should be easy to figure out. Hope the diagrams helped some. Greg Quote Link to comment Share on other sites More sharing options...
datsun40146 Posted May 9, 2007 Share Posted May 9, 2007 This is almost creepy... 3 weeks ago I posted the EXACT same question, here is the link. http://forums.hybridz.org/showthread.php?t=120894 What did you decide on, will the 75' harness work in the in the 77' Quote Link to comment Share on other sites More sharing options...
Mycarispurty Posted May 10, 2007 Author Share Posted May 10, 2007 Even if it does, I'm not going to even try, mine is all dirty and that's way too many wires to keep up with Quote Link to comment Share on other sites More sharing options...
