I've got an 03 gmc lb7 with bent frame. I swapped motor/Trans/tease to an 02 chevy/lb7 frame. I've pulled all wiring from 03 and installed on 02 except cab harness. Truck won't turn over, except jumping starter. I have no instrument cluster at all. I do have radio, dome lights, windows roll down and power seats work. I have 4 or 5 plugs that don't have mate's. I need to get this truck going asap.
