Background info: 06' truck harness, 24x, converting to stand-alone with cable throttle body using 04' GTO PCM. Question: Truck PCM has Blue pins 19 (ignition 1 voltage), and 75 (OFF/RUN/Crank voltage) both pink wires as keyed power to the PCM I assume... Now, the GTO PCM pin-outs only show Blue 19 in use as Ignition voltage, Blue pin 75 is Not Used??? Does the GTO PCM only have one keyed ON wire?? Should I get rid of pin Blue 75?? Thanks in advance!!!

 

I just looked it up on All Data. I see what your seeing. But I don't really know how to answer you. I'm running 03 Harness , 03 PCM with 04 GTO OS. And mine is wired as the truck harness. So not sure if it helps or not...

 

Thanks for the reply! So you have key power going to both Blue 19 and 75?
