How to tell which connector is for IAC or IAT

I removed the connectors to the IAC and the IAT to clean my throttle body. The connectors to the IAC and IAT are the same shape. They can actually be interchanged. One has a shorter length of wire, and they do have different wire colors.

I originally connected the longer one to the IAT and the car would not idle. I'm getting codes P0508 and P0113.

My IAC may have issue as I could have got throttle body cleaner on it while cleaning the throttle body.

I've tried running the engine after swapping the connectors but the codes persist and the engine continues to stall at idle.
I can only get it to stay running if I keep the RPM's high, like 200 or higher.

Does anybody have a diagram with the color designation for these circuits for 2007 Town & Country 3.8L

Thanks for any help!
