Rewiring SR20DE to SR20DET - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hello, I just recently performed my first engine swap to upgrade my 180sx from an SR20DE to SR20DET. Everything was going smooth until it was time to plug in the harness...

The DET harness plugs in fine into the ECU (or the blue plug) however the white plug of the harness (which I was told was called "the body harness") does not plug in

Is there anyone here who has had this experience before? I was told that I would have to do some rewiring/splicing but honestly I'm afraid I'll mess up my only DET harness or blow up my car when I try to start it.

I've been doing as much research as I can for wiring schematics or youtube videos of anyone who knows what wires need to be rewired but no dice.

I'm confused on if I need to rewire BOTH the blue ECU and the white body harness or just the white since thats the one that doesnt plug in. And do I just (for example) find which wire operates the AC on one harness and splice it to the new harness in that same pin?

Thanks in advance for all the help. I can't wait to get my car back and running...its killing me...
