ok awsome one of my main questions is what about the wiring? do i need a new wiring harness? and what about the PCM do i need the one from the truck the motor is commin out of or can i get the one i have right now reprogrammed? will it bolt up to my 4L60E for now until i can find a 80E to swap in? can i use my stock electric fans that i have right now or will i have to a get another set to swap in?
