I have a harness that is missing the IAT from it, and I'm going to add it. Where does the black/brown wire lead to?- I'm guessing a certain pin in the ecu harness? What about the black wire coming from the IAT connector?
Thanks!

 

Look at the wiring diagram in the FSM! Section F.
Show us that you are worthy of owning a FD.

 

Yeah if I was home and had access to a computer I would. I don't want to download it onto my phone since I'm working on it while at work. Thought someone might know off the top of their head. Thanks for the constructive help.... I don't quite believe the ability to look in a manual describes ones ability to be worthy to own an RX7. Show yours and actually help.

 

By the 93 FSM
Green ----> 3L ECU connector
Brown/Black ----> Common Ground Wire from ECU 4D. Same ground wire that connects to TPS, EGR, OMP, IAT, etc.

 

Thank you! Much appreciated!
