Where is Brake Controller Install Harness in 2010 Ram 1500 with 7-Way


I have a 2010 Ram 1500. It has a factory 4way flat and round 7 pole.I see 2 grey plugs under the dash, do I need an adapter from one of these plugs to the controller? or do I have to wire in a complete harness?


Helpful Expert Reply:

Since your 2010 Ram 1500 has a round 7-way connector at the rear of it that means a brake controller like our best selling Prodigy P3 part # 90195 could easily install with the correct harness, part # 3021-P. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.

I attached a picture that points out where it will be as well.
