Where is Brake Controller Adapter Plug Located In 2002 Dodge Ram Pickup

Question

Question:

Hello. I have a 2002 Dodge Ram 1500. I have a 7 pin tow connector in back. I cant seem to find the wires or adapter under my dash to hook up a brake controller. Can you help me? If this is the right picture I was wondering if the Curt brake controller would work on this one? Or can I choose another brake controller I like?

The green connector in your truck is not the correct plug. It is normally a blue plug like what I have shown in the photo that plugs into the adapter part # C51332 if you are using a Curt brake controller like part # C51170. There will be a port to plug into if the truck came with a factory 7-way plug just to the right of the emergency brake.

If the 7-way plug was installed after-market, you will need to see how far the wires from the plug are extended so you can complete the install with part # 5506.

I am not sure which Curt brake controller you are referring to but if you are referring to the Curt Echo brake controller that plugs in line with your 7-way plug part # C51180 all that you need is the 7-way plug to have active turn/stop, running light and 12V circuits. The Curt Echo only requires these functions on the 7-Way plug to function so you may consider using the Echo because it is much easier compared to finding the wires.

@Mike It’s possible that your truck just didn’t come with a factory trailer-wiring harness at all. Some 2002 Dodge Rams, especially those without the factory tow package were built without the under-dash plug or the blue brake-controller wire. If you’d like to install a brake controller, you can still get everything set up using part # ETBC7. That kit lets you convert your existing 4-way into a 7-way and provides the wiring you’ll need for the brake controller circuit. If you don’t already have a 4-flat connector, you’ll want to start with that first: For a 1500 without the towing package: use part # C55504. For a 2500 or 3500: use part # C55329. Once those pieces are in place, you’ll have all the wiring you need to install a brake controller and get your trailer brakes working properly.
