An under hood wiring diagram for the Dodge Ram 2500 can be found in its service manual. A copy may be obtained from the nearest Dodge dealership.
There should be a diagram under the hood or in your owners manual, if not go to the Chevy parts man and he can print it out for you.
It should be located on the radiator support under the hood.
