Mopar Brake Controller Wiring Harness for 2010 Dodge Ram Brake Controller

Question:

Hi I am wondering if you sell the small adapter for the mopar brake controller that fits in the dash? I need the smaller of the two plug ins that plug into this unit, I am noticing that I am missing it under the dash and cant find it anywhere! if you have any idea if one of your plug ins fit this that would be greatly appreciated!

The brake controller wiring adapter you referenced, part # 3021-P from Tekonsha, is intended to connect one of their brake controllers such as the Prodigy P2 # 90885 to the under-dash connection port found on many tow-capable vehicles. This one 4-wire harness provides all of the required input and output signals to connect a brake controller, including +12V power (black wire), brake light switch signal (red wire), ground (white wire) and the controller output for the trailer brakes (on the blue wire).

My technical contact at Tekonsha confirmed that this blue plug is the only means he is aware of for plug-and-play connection of a brake controller to your 2010 Ram.

Dodge Ram trucks usually have a blue plug located under the steering wheel, just to the right of the emergency brake pedal for connection of a brake controller. Please refer to the linked photo. I also have linked a detailed article on the subject. If your truck has a factory 7-way then the blue connection plug should be under the dash. It is possible that the harness has been tucked in, taped or zip tied to other wiring; it is not too uncommon for a bit of searching to be required to find it.
