Here, look at this. This is essentially how and why it was spliced in for the 94 body.

Pin 53 on the ECU is for the EGR temp sensor, and pin 6 is for the EGR solinoid valve. Pin 53 is a 5v signal wire. You do not want it hooked up like that, thats very bad.
I understand, but that pic is of a 94 ECU. You 91 doesnt have those two transistors in it that ground pins 3 of the relays, instead you are sending 5v and a ground signal from pin 6 of the ECU that would normally run the ECR solenoid valve.
I don't understand why or how that guy pulled it off like that in his thread. Obviously it worked for him, and he used a 91 ECU/harness in a 94 base. EXACTLY what I'm doing. How did he pull it off?
Hey Corey, I'm gonna start a new thread. This one has gotten way too long, and I am utterly confused in the last 3 pages. I'll just unclutter it all with a new thread.
