Ok, need some quick advise for my new prodigy. I have a Y2K 2500 and just picked up the Prodigy and the wire harness that lets you plug from the dash right into the Prodigy. My question is Prodigy says to ensure Dodge has grouned the trailer Package plug directly to the battery. Do any of you know if this is done. Or has anyone use Prodigy's wireing harness with a Y2K. It seems so easy i think i'm missing something
