renix to obd1

Recommended Posts

so ive looked and looked and i haven"t found much info. so i finally did my ho swap... but its in a 1990 renix. now I'm sure many of you know renix wiring leaves alot to be desired.... now i have a 1992 comanche complete... minus alot of stuff... but the full wiring is there. is it worth swaping harneses over from the renix to the 92? yes i know its alot. I'm also planning on installign ac that will be coming out of the 92.. so dash and everything will be apart so thats the time to do it. i have everything i need. but is it worth it? i have a starting issue i can't seem to nail down either... thoughts?

I think that really depends on what you have left in the 92.

 

As much as I hate to say it, you're probably better off getting a 92 XJ and swapping the harness into the 92 MJ, rather than swapping the Renix stuff in.

The '92 wiring will have a LOT of small advantages and some big advantages over '90 wiring. A real exterior fuse and relay box, organized wire runs, the feeling that the thing may have been touched by an actual engineer, etc. Is that all enough to make me want to swap a harness? Maybe if I had to remove everything anyway or was starting from an empty shell. I don't think I'd rip an entire (functional or repairable) Renix harness out of a truck and swap it with an HO harness on its own, though. Lots of changes would have to be made - it won't just slot in unless you swap literally everything from an HO donor.

 

One thing I would NEVER do is backdate an HO vehicle to use anything Renix. Even if it's all I had. I'd rather build my own harness than swap Renix wiring into anything it didn't come in from the factory.

I would.

 

If I ever see a super clean 97+ XJ, for the right price, I'm going to Renix swap it. :dunce:

Renix is simple and it's quirks are well documented and easily remedied.

i guess maybe i wasnt specific.. sorry. i have a running and driving 90 that has an ho motor in it with a renix ecu. hard starting tho. trying to figure out why but not solving it. i have a 92 comanche i have been slowly pulling parts from. it still has the complete wiring harness ecu dash everything. i plan to pull dashes from both jeeps and swap interiors. ( 1 is grey one is red. i like the grey more) at the same time i am putting in ac. now being that everything will be apart thats the time to swap ecus and wireing if.... its worth it. otherwise i won't bother. otherwise ill just leave the renix alone. but i would like better starting and a cleaner wiring system..
