Hey everyone, I’m doing a frame off LS swap in a 77 GMC. I bought the 5.3 engine from a friend who didn’t know what it came out of. I’ve determined it is a 2001 with a DBW system. It came with the harness and ecm (09354896) I’m having a hard time finding what TAC module and gas pedal I need. That being said. Does anyone know what part numbers I need for these? Salvage yards haven’t been much help. I’m pretty sure it has to come from a 1999-2002 only, but there’s several part numbers in those years. Any help appreciated.
