Power 7 Way RV Connector Pictured below is the Pollock 7 way connector, which is the connector style in most common use on RV trailers and is becoming increasingly popular on horse and utility trailers. This connector is also manufactured by the Theodore Bargman Company and there are also some generics around. They are supposed to be interchangeable and the wiring color code is maintained among the various brands. As you can see in the illustration below the back side of the connector body is labeled at each terminal. The labels are listed below with the function assigned to that pin. On the tow vehicle side with the exception of Ford and Dodge pickups and SUV’s with factory installed trailer wiring, wire color alone should not be relied on, always test and match the function to the appropriate terminal. On the trailer side RV’s for the most part are wired to match the connector colors. Any plug that has been changed or extended, along with horse and utility trailers should be tested when replacing for any reason to be sure the function matches the terminal. It should be noted below that the center terminal is labeled as an auxiliary circuit, most commonly used for backup lights not a ground terminal as many try to make it. Also after the connector diagrams find more information on wire colors used by GM, Ford, and Dodge.

It is sometimes necessary because of the legal requirement for trailer lighting. Furthermore, from a technical perspective, it is used for wiring the two vehicles together to power and synchronize their lighting systems. A trailer light converter assists in adapting the differences in voltage and the number of wires. Most basic trailers in Canada and USA usually have only one light with one wire on each side that functions as both a turn signal and a brake light though sometimes there is a separate yellow and red light for signal and brake lighting.
The brake signal from the towing vehicle usually needs to be received by the converter and then sent to both the left and right trailer lights.

How to wire up the lights & brakes for your vehicle & trailer
Cars are not usually used for towing so they dont include anything to make hooking up the lights easy.. I would recommend not splicing the wires, you never know what will happen.

I ran 10 gauge wires to the rear for these functions, as I prefer heavier wire than OEM anyway. OEM used to be 14 gauge in and later they upgraded to 12 gauge. By tapping into the cab end of the connectors, you can access the power leads that you need from the front harness which has these functions even in non-trailer-towing trucks. This setup with 8 gauge wires allows charging the trailer battery “on the road” much quicker than the stock 12 gauge wires would.
