IAC Wiring?

Hey guys,

Im installing the IAC valve on my car and I dont have an existing plug or connector from an old harness. I dont know which male prong on the IAC gets the signal wire to the ECM and which gets +12v.

Can anyone confirm which is which?

12V (red wire) goes on the clip/lock side of the plug. ECM pin 37.

I have a picture of the plug, if you need it PM me.

For everything that is worthwhile, there is a counterfeit.
