So I’m in the process of putting my 521 w/ C-6 in my 1994 mustang. The car originally was a V6. So my question is the cars wiring. Do I just need to disconnect the engine harness and tap into rest or pull all of the factory wiring and start new?
I would just remove the old engine harness if this is a hot rod or race type application keep the alt, fuel pump fans and start circuits or just remove everything if it is not a obd build and wire it up and go
