I had a non-IAC Holley 670tbi. So I drilled some holes and added an IAC. For clearance I had to turn the TPS around so it pointed forward. Holleys TPS has a different connect then stock so which place does my blue, white and black wire connect?
Also since the Holley injector wires are black and the factory are different colors does it matter which way I splice them together? Or should I just make sure that two of the wires going to one factory injector go to one holley injector and the other two to the opposite.
