Questions and Comments about this Question
Question: Could a round 5-pin connector be used just as well and not have the center pin to eliminate? I have a 5-pin but just have not installed it yet. I plan to get a trailer camper with a brake setup and wondering if the brakes cannot simply be connected to a brake-light wire as mentioned above. \Thanks....

The outline above is referring to brake lights, not the signal for electric trailer brakes. Tying the trailer brakes to the brake light function on the connector would mean that the trailer brakes would engage at 100% strength and lock up when the brake pedal in the truck is pressed. They would also engage at 100% strength with the turn signal as the brake light and and turn signals are carried on the same circuit.
To operate the trailer brakes, you need to have a brake controller inside the vehicle with a dedicated circuit that runs back to the trailer brakes. I have added a link to a brake controller FAQ that will get you started. Patrick B - 3/28/2013
