2004 Dodge Ram 2500 - Which Wire Is The Cold Side Of The Brake Switch?  

On my 2004 Dodge Ram (which would be the same as your 2003) the factory trailer connector plug split off from a larger wiring harness on the inboard side of the drivers side frame rail near the rear bumper. There should be a rectangular connector…

Normally you can find the brake light switch under the dashboard at the top of the brake pedal. There could be a number of wires attached to the switch so you can use a tester like part #PTW2993 to test the wires. Since the auto manufacturers can use…

We have everything you need to install a brake controller on your 2004 Dodge Ram. Since your truck does not have any factory trailer wiring, we will want to install a trailer connector first because the brake controller will tie into the trailer…

You can add a 7-Way trailer connector and retain the use of a 4-Way as well by installing #37185. The 4-Way you have will plug into the 37185 and the remaining wires would have to be hardwired in. The white wire grounds to the truck frame. Black is…
