I got rid of my harness and ECU for my 95 wrangler. However i did not save what wire went were on my fire wall. I have a black wrapped group of wires that comes out of the center of the fire wall, also I have the inner group of wires that are next to the headlight/turnsignallight wiring harness plug in (drivers side between brake booster and fender). If anyone has a diagram or knows of a thread, i looked for a bit now and just can't find one.
Try to do some digging online for the FSM for your Jeep. I have the FSM for my 1990 and it has exactly what your looking for and so much more. Wish I could help more than that, but the bulkhead connector is completely different between the 1990 and 1995.
I may be wrong but I think you can cut the entire wire from the center of the firewall out. The sensors and ignition wire comes from the bulkhead fitting below the master cylinder. At least that's how my 88 was
