jeep_freek88 Posted March 25, 2009 Share Posted March 25, 2009 Pleas help me I need a wiring harness for my 1989 jeep comanche 4.0 inline 6 5speed. Does anyone know where I would be able to find one and also any tips, hints, or words of wisdom on wiring? p.s. its the under the dash wiring harness with the fuse block. Thanks in advance :cheers: Link to comment Share on other sites More sharing options...
wolfpackjeeper Posted March 25, 2009 Share Posted March 25, 2009 any 1990 or older cherokee or comanche with a manual transmission and that motor should do. I think anything older than 1995 would work with a little splicing. Link to comment Share on other sites More sharing options...
Boilermaker Posted March 25, 2009 Share Posted March 25, 2009 I think anything older than 1995 would work with a little splicing. You'll probably want to stick with a harness from a '90 or older renix 4.0. I'm pretty sure the bulkhead connector and gauge cluster changed with the introduction of the HO in '91. Don't even know if it would be possible to make it work, but probably not worth the time if it was. If you find a suitable harness from an XJ, a little splicing is required. XJs have two connectors that run to the rear cab harness, MJs one. The wires you need are all there, its just a matter of moving some pins around. I believe you would also need to run a wire from the brake pedal to the steering column so the brake lights work correctly. There are a couple of threads about the swap around, along with some wiring diagrams that should turn up in a search. Link to comment Share on other sites More sharing options...
mjeff87 Posted March 25, 2009 Share Posted March 25, 2009 I've got one that I was holding for another member but he hasn't gotten back to me in quite a while about it. It doesn't come with the ECU, though, just the harness. Shoot me a PM if interested. Jeff Link to comment Share on other sites More sharing options...
