Pin 4 on the ECU goes to the black wire on the IAC valve, the other wire on the IAC goes to 12V (when ignition is on)

Could be, I havent looked at the car in probably 5 months, and its in storage across town, plus mine is an RB26 so im not sure if the colors differ.

ok, its just on an rb 20 (not sure about others) black with red stripe is ignition power for the ecu and the blue with green stripe on the plug is the same color as pin 4 on the ecu. so i hooked it up this way and it seems to work.
