Fan trigger pins on truck pcm? I was just looking at the diagrams for my harness. There are no fan activation pins on my harness. (it is a 2000 truck harness)So i started looking at my pinouts for the ecm still not listed.I think i remember someone saying that it could be turned on in the ecm, with hp tuners. would any body know witch pins would be the triggers for the fan relays when it is commanded on?

You should post it in here too, so that when people use the search and this thread comes up, they will have their answer. The search tool on this site is pretty awful.

First stage fan- Green Wire, Pinned at Blue 42
Second Stage Fan- Blue Wire, Pinned at Red 33 or Green 33
Remember that you will have to add a relay of some sort and tap onto the compressor voltage to force a fan on if you are running A/C. This will prevent catastrophic failure if you are not utilizing a pressure switch.
