i recently purchased an h2 for an amazing deal with the intent of converting to a duramax i have a complete lb7 with tranny transfercase wiring etc, but im not sure if i should just purchase an insurance write off, anyway is there anyone that can adapt the harnessess of the vehicles to make 1 for the h2 or can i buy a custom harness? i dont mind doing all the mechanical work, ots just adapting the harness and making the ecu communicate that makes me a little queesey! btw i do have access to efi live and kennedy tuners and a tch 2 if that helps. thanx! help me build my dream truck!!!
