Jerijan, You really need to get a factory manual for the truck. You are well beyond what a Haynes or Chilton's manual will help you with. You can either order one from the dealer or use http://www.alldatadiy.com/ (they provide them electronically on a subscription basis). I used to have a 96 Ram and I bought a factory manual for it. The factory manual is about 4 inches thick and well over half of that is electrical stuff. It will show you exactly where all of the grounds are at and outlines all of the test procedures.
