Where Does a Brake Controller Plug Into on a 2006 Dodge Ram 1500 Big Horn


Cant find brake control plug under the dash near e brake? Please help

On the 2006 Dodge Ram 1500 that came with either a factory 4-Way or 7-Way trailer connector the receptacle to plug in a brake controller with a harness such as # 3020-P will either be on top of or along the side of a white rectangular box back along the firewall to the right of the emergency brake pedal. I have included a picture showing this for you. The factory plug is blue.

If your Ram did not come with a factory installed 4- or 7-Way trailer wiring harness then it is possible that the plug is not there and the controller will have to be hardwired in. I have included some additional links that will also help.

I have a 2006 Ram 1500 5.7 mega cab. I see the blue connector to the left of the emergency brake pedal. What has me confused is that I have a 4 pin connector at the hitch of the truck. If I have a connection for a brake controller in the cab, should I also have a 7 way pin at the hitch?

The 2006 Dodge Ram came equipped with a factory brake controller plug-in port whether it had a factory 4-Way or 7-Way, so what you're seeing is actually correct. You will still need to upgrade the 4-Way to a 7-Way connector through. Using the Wiring Kit # ETBC7 is still a good option, as the factory blue brake output wire doesn't run all the way back to the bumper - it stops at a connector that's located under the driver's side wheel well. You'll need to tap into this wire and run it back to the 4-Way/7-Way connector.

@ChrisR , thanks for the response. After looking through the interwebs, I found in a dodge forum that it was a green wire under the fender well of the driver side that stops at the connector. I was able to successfully get my truck wired. Thanks again, I hope these posts don’t confuse anyone
