Anyone know of any place other than dealers to buy new OEM replacement wiring harnesses for Renix XJ's?

I got mine at the junkyard from a renix with extremely low miles. There is also a company called painless wiring.http://www.painlesswiring.com/
They can make custom harnesses and have parts of our renix wiring such as ignition connectors ect. Probably going to be a pretty expensive ordeal any way you go.

Good luck

you can also try TeamCherokee.com they have lots of older Cherokee parts
