02 to 00 Engine Harness Swap going backwards?

[CJ_]

So I'm wondering if this is even worth it or do-able.. I posted in my thread, but want to get a little more feedback.

I ended up with a really good condition harness for a 00 with Bosch Maf harness, my car is a 2001.5 Hitachi Maf

I installed as many connectors as I could and went to crank it - nothing.

The main differences are:

-> No plug for back of alternator on 00 harness

-> EGT sensor on driver side (not a big deal, might have them deleted anyways)

-> Plug for starter (i think) is different (passenger side firewall) 2 wires on '00 harness, 1 wire on '02 harness

-> No oil pressure sensor plug on 00 harness (front of driver side bank)

-> Bosch Maf sensor would have to be converted to Hitachi Maf Sensor (not a big deal)

-> Ground moved to other side (not a big deal)

I would really like to make this harness work, any input?

I did this with an o2 a6. I bought an 00 parts car and used the engine and the harness. My problem was the connectors under the ECU had to have a few wires repined to go to the right places. I still don't have cruise control but it's running. I had nothing when I tried the first time as well. I think I changed 7 or 8 wires. Also 2 of the connectors under the ecu were actually different and wouldn't plug in. The white and red one I believe. After finding the plugs ( I sold my engine and harness like a dope) And repining all of those there were the 7 or 8 different locations. Good luck

All of my plugs connected under the ecu, the one I'm stumped on is the different starter connection

Yeah sorry my grounds, alt, starter and all were the same
