Hey, anyone know what the pins are the output wires that run the fans on an 04 GTO harness?

I used an '04 GTO harness and computer, it was pin #33 Blu/Wht Cooling fan relay on the green plug

Pin 33 on the Green connector is the high speed fan relay wire. There is no low speed on the 04 GTO harness. It comes from the BCM. You can have the PCM programmed to have pin 42 on the blue connector be the low speed fan relay. That is what I did and it works fine.
