check wiring on your plug make sure the wire on your truck that has power when you press the brakes is connected to the wire for the brakes on the trailer Remember you must have a brake controller installed in the vehicle, just because the vehicle has a "tow package" does not necessarily mean you are ready to tow a trailer with electric brakes. The only vehicles that currently have this capability are the late 05 and 06 Ford trucks f-250 and up, and that is an option that must be ordered when purchasing the vehicle.
