This is just an idea I had after dealing with wiring nightmares. I'd like to put a database of wiring connections from various years and engines into a sticky. I will contribute C100 C207 both sides for an 88 Formula and TA if this takes off. This I believe would be helpful to alot with wiring woes, engine swaps repairs.... Lets get some input and see where this goes. Post your confirmed stock wiring with year make and model.

Example:
88 Formula LO3 - C207
Dash Harness Side

ECM Side
