hey all new to the forum and hoping to get some help. I just picked up a 97 3500 dually originally had a 7.4 but was swapped with and 8.1. the original wire harness is still in the truck and I was hoping if anyone has made this swap and used the same wire harness you might be able to share and information on pinning, etc. I am trying to rebuild this truck with very limited knowledge and I am hoping to lean on the forum for guidance.
thanks in advance<
