Default swapped harness now truck wont start

we just installed an engine into a 2000 silverado. truck ran fine.truck was a base model with no power inside. we had another truck siting around that was power everything so we swapped the dash harness so we could have power inside. swapped bcm and ignition switch and lock cylinder and air bag module. truck fires up and dies instantly.
