1994 yj heart transplant
I have a 94 yj 2.5l 5 speed, i work at a larger junk yard and have plenty of 4.0L out of cherokees and grand cherokees.. i have my engine,trans,tcase,driveshafts,radiator out of a salvaged 94 wrangler but i got there to late and they sold the harness and ecm... my question is does anyone know if i can use any other ecm and wiring harness????
Yes you can. The XJ OBD1 and the YJ are the same. Make sure that you are getting it for the right engine. 91 and later under the hood are the same but you will run into complications with the IP wiring between the years. Especially the bulkhead, ignition switch, and cluster. What year YJ are you starting with? Your in Adrian Michigan?
Engine is out of a 1994 xj.. so its just plug and play?? my jeep is a 94 2.5l stick and the xj is a 4.0l auto.. i am taking the wiring harness from the xj and the ecm from it too... will it just plug in at the bulk head and will my gauges work??? thanks again
No, there are some wiring differences. Close but no cigar. Your wiring harness will work. You just need to swap the ECU and add 2 injector wires. The auto trans had the nuetral saftey switch so you jumper those pins on the ECU and you should be good to go. No need to swap the wiring harness at all.
If you need help with the injector wires and jumping the nuetral saftey switch I can give you a hand. Maybe we can do a little documentation. I know this has come up before. I havent done a writeup here yet. It seems like it would be a good one to do.
