What Tekonsha Brake Controller Harness Is Needed For A 2010 Dodge Ram 1500

Dodge switched their brake adapter pin configuration on the Ram 1500 for the 2010 model year.

If your 2010 Dodge Ram 1500 has the factory 7-Way connector you will just need the Tekonsha Brake Control Adapter, part # 3021-P. This will plug into the back of a Tekonsha brake controller and the other end will plug into the brake controller port located under the dash on the drivers side, just left of the steering column, and near the emergency brake pedal.

If your Ram 1500 has the factory 4-Flat connector you will need the same # 3021-P adapter mentioned above and the Hopkins Adapter 4-Pole to 7-Pole and 4-Pole, part # 37185. The # 37185 adapter will plug into your 4-Flat connector at the rear of your vehicle, to give you a 7-Way connector, and the four remaining wires will need to be hardwired to the corresponding circuits on the vehicle.

The white (ground) wire will need to be attached to the vehicle frame, the black (12 volt power) wire is connected to the vehicles battery with 10 gauge wire like the # 10-1-1, through a 40-amp circuit breaker # 9510, the blue (trailer brake) wire will be connected to the blue trailer brake feed wire on the brake controller, and the purple (auxiliary) wire is for reverse lights if you need that circuit. If any of these connections are not needed just wire tie them up out of the way for future use.

I am including a link to the installation instructions on the brake controller adapter and a video link of the # 37185 adapter being installed on a 2006 Dodge Ram.
