I am in the process of swapping my auto for a NV4500. I've got all the nuts and bolts stuff finished. I was wondering if anybody could help with what I need to change electronically. Do I need to reflash the pcm and/or ecm? What do I do about the neutral safety switch? Can I just simply bypass it? And is there any thing else that I am forgetting about to finish this swap? Thank you for your time.
