What do you need to do to replace the BCM in an '04 GP? I suspect it's related to my fuel pump issues, and would like to try swapping it with one from another '04 we have. Will it bork the security system (different keys) or need to be otherwise programmed? Or can we just swap them and see what happens (the current plan)?
I don't mean about physically swapping them, but if there is any programming required or anything else electrical to do. The cars are similarly optioned, so I expect windows, seat controls and lighting to work the same.
Thanks!
