Thanks Tim, I did call AMP and though he really couldn't help with a diagram, he stated that I would have to use diodes ( Ok above my pay grade) as the steps uses a negative ground to operate and taking it off the dome would require positive activation and that you would have to prevent back feed. Suggestion also was made to use the door locks as power. I just wish there was a clear diagram as to wire this and I agree with a SPDT lighted switch
