Look for an ignition fuse in the inside fuse box next to dashboard. Could also be a wire in the main harness that plugs into back of trans. I have seen them pinched at the crossmember about 6 inches back from the connector.

Last time switch everything out of my truck. We removed the Copilot some how buddy screwed up the pins 2 of them in the tcm and truck would start then shut down.
