IAC Wiring

[Bill Lankford]

Hi guys,

I could use a little Fast wiring help. The thorttle body I am using came with a different IAC connector than the Fast harness uses. It is Delco # PT757 or GM #12126487. It is a 4 pin flat connector. Can anyone tell me how this wires into the Fast harness?

Thanks,
Bill

The FAST harness has a square plug on it labeled A, B, C, and D. The connector on your IAC motor is labeled this way as well. Connect them as follows:

A on square plug ---> D on flat plug
B on square plug ---> C on flat plug
C on square plug ---> B on flat plug
D on square plug ---> A on flat plug

Thanks Craig, now I can get started.
