Those with a PSI coneversion harness, have a question
I have a PSI harness and was hooking it up today. I have a question for those of you who've used their harness before. I have the harness for the 98-02 vortec DBC for a truck. In the instructions, it shows a IAT Sensor, but my harness doesn't seem to have that connection. Is it not needed on the trucks?
