Brake Controller and Trailer Wiring Setup for 1995 Dodge Ram 1500

Expert Reply:

Congratulations on your new truck! Since brake controllers are for electric brakes, boat trailers generally do not have electric brakes due to them being used around water. You have a 4-wire connector on your boat trailer, so you would not have hydraulic brakes either, probably because it is light enough that they are not needed.

Under your dashboard, the 6-wire plug is for the brake controller, while the 2-wire plug is most likely for computer diagnostics. To use your boat trailer lights, you will need to install a T-One Vehicle Wiring harness with Four Pole Trailer Connector, part # 118329. We have an excellent video that shows this wiring harness being installed on a 1999 Dodge Ram 1500.

After installing the T-One wiring harness, simply plug in your boat trailer 4-flat connector into the 4-flat plug on the rear of your pickup. This will give you turn signals, brake and running lights.
