Howdy, Gerry, and welcome to the Ram ForumZ. I'd encourage you to stop by the Newbie Checkin
section and introduce yourself to that other members can give you a proper howdoyado.
As for the wiring scheme, if some other members don't chime in, check the internet, see it your local dealership can help you out or buy a manual. Buy a manual and reading up on your truck would be the best way as it will allow you to get to know your truck better.
