you wont be bothered with a bcm on an 01, as I have an 01 5.2 in my dart. what you will have check for is a factory security system. mine didn't have it, but if yours does, the computer will have to be reflashed for it to run. dodge place told me if you have an ordinary key, it doesn't have security. or at least that was the case for me. this swap is really easy to do if you have the patience to sort out all the unneeded wires, AND, have the pcm box . there's a ton of info on this swap in this section. if I can help just holler. dave.
