Default ProjectGS DIY: ECU Pinout

A few of you guys have asked me to post this. There were some errors in the pinout before, but now I corrected them. This is commonly used to install piggyback fuel controllers, standalone ECU's, o2 simulators, building custom wiring harnesses, or just for general troubleshooting.

Also, 2001 was the mid-year changeover, so just compare the 2 diagrams to see which ECU connectors your car has if your car is a 01.

I have a GS400 one that's halfway complete, but no GS430 yet. I can make new ones when I have some spare time, it just takes me about an hour to draw these up. Check back in a day or two and I'll try to post it up if I have time.

I have pin out for 430 that I did when I had a harness made. It is not as nice as Jefftsai's. What are you looking to hook up? Do you need ignition & knock sensor location?
