I'm looking for a pinout for a 12576106 PCM . I reflashed the computer to a 04 GTO Tune.... The PCM was from a 03 GMC Yukon.

I can't figure why I can't get the fan to turn on. Looking for what pin , so far I saw two pins on Lt1 Swap... But no luck... I'm using the computer to flip a relay to turn a flew a lite syclone fan...

Well since my link didn't help any, how do you have your fan relays wired up?
