Engine Compartment Electrical

[Tanner]

Has anyone done a complete re-wire in their engine compartment? Mine is a mess and there a quite a few wires with their coating worn through and connectors that go to nothing (it is quite possible that they are supposed to, however I've checked everything I thought they could belong to with no avail) so I just would like to hear from some of you who may have also had to do this.

IMO If its as far gone as what you say, i believe the best option is to find another harness out of a JY. But if the truck is running/driving without issue i would first try to salvage your current harness before going through the trouble of tearing the whole thing out. Its really six of one half a dozen of the other work wise. Electrical work is extremely tedious, so don't get discouraged. When i was "restoring" my MJ i too had the inclination to remove and replace, but instead decided to salvage. I ended up having the engine harness strewn across my entire living room for several weeks fixing, recrimping, and rewrapping.

 

If you decide to go the replacement route, i believe you will have a much easier time finding a donor since your truck is an automatic. Any RENIX (87-90) 4.0 cherokee that is also an auto will be a direct fit for your MJ. I do recommend you seek out a NON C101 harness, as they are all to often the source of many electrical issues.

 

Best of luck.

It is running and driving with no current issues, I'm more looking at the options as preventative measure. I would obviously like to avoid fires, hence my contemplation of replacement, thank you for the info and advice. Pardon my ignorance but c101?

I soldered my crimpded connections, replaced frayed wires, and re-wrapped my harness with new split loom and friction tape. I was able to salvage most of it, but did replace a surprising amount of connectors and wire.

Yeah that may be my best option at this point. I've been looking for a harness to replace it with now luck so

On the bright side, you really learn how your truck works when you do this.

That's true, silver linings I guess haha
