As I'm starting to have to trace more and more wires in my CJ7, as well as having a new dash and re-wire on the winter to-do list, I decided to take the time to color in the CJ wiring diagram. As all I could ever find online were black and white images of the OEM wire diagrams, I traced all wires and colored them according to what was labeled to make things easier. Everything should be pretty close, and hopefully will provide everyone a much easier reference when working on any CJ in the future. Enjoy.
I'm about 60% done making a CAD file from one of the old jpeg images. Based on enthusiasm here for colored markups I'm guessing a live CAD file may be of use to some? Especially handy if you have CAD and want to change things to match your existing Jeep... I plan to make each wire a polyline, meaning that if you select it in CAD then the whole wire is selected, from end to end. Guess we'll see, I've been chipping away at it when other Jeep stuff isn't more pressing.
This is the third, or fourth, time in the last week that your pics won't post for me, but no one else seems to be having problems with them. What's weird it's only your stuff that I can't see. No problems with any other posts from other members.
Am I just a retard? Is it a Mac/PC thing? Or my slow-azz satellite connection? Forum server? :dunno: Any ideas?
Does anyone still have the PDF file for this diagram or can you direct me to it? I can not find where I saved it a few years ago and a friend od mine is in the process of rewiring his cj5. Much appreciated. I sent PM to Waterdog but his box is full.
Here you go. If it does not work I can email the document. I had to shrink the size to get it to up load on the forum. I cleaned out my Box so if need you can PM me you email address.
I also have a question regarding the 1978 color diagram that you can find out there. What is this item circled in red? I don't believe I have that in my 1985 CJ7...
Do you mind just briefly explain what the codes mean? or what they correspond to? Sorry for the noob question. Just wrapping my head around everything before I start tackling the re-wiring job.
The numbers are circuit numbers that you would find in most schematics of the CJ. I was just pointing out the circuit number's colors stayed the same up until 1982. Then they started to mace changes in the nomenclature although the colors and gauge remained mainly unchanged.
The Letters on later CJ's matched up with the letter designation on the bulkhead connector.
Hello,
In going through this post I ended up a little confused. The original poster seems to have been working on an 83 CJ7 (or at least that is the only model in their signature). Can someone clarify what years this diagram covers? I am working on an 83 CJ7 that was left out in the desert for about 15 years and I am working to solve some light issues.

Ok I know this is old but it is awesome. I just solved a backup light problem in less than 30 minutes. I know I am going to love this site. I have found a ton of information already just with the search function. This is my second jeep and it seems over the years the PO's just can't keep control of the wiring and though my current is no where near as bad as my last one it is still a mess.
I just got a Jeep project which is part CJ5 1956 (Frame and various dash parts) and part 1978 CJ7, otherwise. However, it's a mess, clearly used as off road and farm vehicle, not up to CA code, and once I removed the custom dash I realized most of the wires are missing or cut, as well as an oil pressure gage wire off the 289 Stock Ford engine inside. See, a mess. So this diagram was a big smile for me, as I ordered an OEM harness to go with my OEM jeep dash. Now, just to figure out the 56 dash mounted ignition with my CJ steering column with no ignition key switch...

Great post!!! Wondering why I didn't find it sooner. The color coded drawing is so helpful. Thank you!
