Wiring harness
 
So, I need a little help. I got me a killer deal on a CJ 5 75' few weeks ago. Need to install wiring harness which I have. Maybe someone can explain to me where to even start??

That's something that's going to be difficult if not impossible to explain on a forum. Myself, I would start by tearing out the old wiring and replacing with new. If your not real comfortable with wiring or if you've never done anything like this it's going to be a project for sure. Good luck!

I will assume that the old harness is not there.... This is a CJ so the wiring is fairly old school which means simpler than the newer Wranglers.

You did not mention which harness (engine? tub? dash?) In any event the length of the wiring usually tells you where the ends go. They don' make the wires longer than needed.

Yes, the old harness is out and is the harness for the engine. Any know how to which to even began?

Go into your profile and fill it out please.

That way we aren't guessing what you have for a jeep.


What engine/tranny? 1975 Is old as far as information online goes but you never know. I'll see what I can dig up but on the older Jeeps I have vey little from that era.

I have this for a 1978 CJ. They did not change much over those three years. Maybe this will help you;

Get all your ducks in a row. When I did my '74 I rounded up a new ignition switch, did the headlight relay mod, went to a CS130 alternator and H4 headlights. My kit was color coded for Chevy. 14 circuit was too much, probably could have gotten away with 10.

Thanks for the diagram! That's something to get started with. Can't thank you enough!

No problem!

I figured that the 1975 to 1978 CJ's wiring didn't change very much. Even if it is partially accurate that gets some of the wiring plugged into where it needs to go.

KEEP IN MIND that the wire colors may not be correct. :eek:
