ECU Harness, red/white wire goes where? Options

[6gsillyca]

So I pulled my ECU yesterday, and in the process I accidentally pulled one of the pins out...

Hoping one of the wiring guru's can help me out and tell me where this belongs.

Thanks Lagos. Is that how I would go about re-pinning the harness aswell?

Yes, however some plugs (like the ecu plugs) have a different way of unlocking.
ECU plugs unlock like this..


Also, once you unlock it, you have to use a pin or needle to pry up on the pins inside the plug to pull them out.

I currently have 2 ecu's (one came with car, and second I picked up off mr2oc). The one that came with the car, is a 17321, which I understand is a jdm ecu from 90-91. I was told this ecu may have been chipped (blitz, mines etc) as it came with 550 installed on the clip. This ran the car fine, except I wanted to put stock 440's back, in an attempt to try and regain some mileage.

If you unscrew the top cover of the ecu, you should be able to tell if there is a Techtom board installed in it or not.

I didn't check your part numbers, but a 90 ecu/harness should not be able to run in a 93 ecu/harness without being repined. Here are the differences between the two harnesses. I made this little chart when I converted my harness to run a 93 SARD ecu.
