89 Civic ECU wiring
Boy do I feel like a noob. 
Ok, the pin that should be going to the TPS is not going to the TPS. The pin that should be going to the MAP is not going to the MAP. The pin NEXT TO the pin that SHOULD be going to the TPS is actually the TPS signal wire. The MAP is in a completely different spot. Why is this different from other 88-91 Civics? The other wires seem to match up, but I guess I can't be 100% sure at this point. Should I not be looking at the diagram from Apexi? I compared both the old and the new updates and H1 just doesn't match up with what I am getting.
Any help?

Re:89 Civic ECU wiring
Somebody has to know something about this. 
I made a drawing of the wires on my harness. Can anybody confirm if this is correct or tell me what wires I need to be using?

Re:89 Civic ECU wiring
That didn't help me.
This sucks. The AFC intructions/manual is wrong. I'm glad I didn't just cut into it thinking it was right.
Nobody else has ever seen this?

Re:89 Civic ECU wiring
Wait... what?
Are you asking for an ECU pinpout?
http://www.hasport.com/Tech/Wring/Co...1%20DX-SiR.htm
Always connect based on the ECU's pins... not wire color, anything. Also, I was under the impression that A'pexi didn't have a wiring diagram for 4th gens(?).
Just match up whatever wire it is.. to what spot on ECU where it's supposed to go. The above pinout should help ya.
