Help, where do these connectors go? (Pics)

It's been awhile since I took everything apart and can't remember where these plugged in. They are on the passenger side of the motor. I know I should have labeled them, lesson learned.

Ok so I found where #1 and #4 go. 2 and 3 are still a mystery.

2 goes to the TPS sensor (side of throttle body). 3 is the coolant temp sensor (front of the intake).

1 - IAC = Idle air control = bottom of throttle body.
2 - TPS = throttle position sensor = passenger side of throttle body
3 - AC = air conditioner compressor
4a & b = air diverter valve. I believe you removed these, otherwise they are near the AC compressor.
