First off let me say I'm new to the forums. I've been lurking around and found a lot of info and tips here! Second, I have a 1999 Cadillac escalade and need a engine harness. The one one the driver side that plugs into the ecm(computer) I believe. I've called the dealer and it has been discontinued so I was wondering would any 5.7 vortec harness work? Which ones are compatible? Does anybody have or know where I could get one? Any conversion to run a different one? Thanks guys for the help in advance.
