I have a 91 Comanche with a 4.0 and aw4. I accidentally damaged part of my wiring harness near the back of the cylinder head (mostly the section that splits off to the injectors). I need to source a replacement harness. I've tried splicing it back together but I cannot identify the wires anymore because of the angle grinder damage. Would an XJ harness swap over? I would liely just swap over the engine side and leave the headlight section alone. Any advice? By the way, I live in Guam so there are not many salvage yards here in the area. Thanks
