A trailer wiring diagram maps the electrical connections between your tow vehicle and trailer, showing which colored wires connect to which pins for lights, brakes, and auxiliary power. The four most common connector types are 4-pin (basic lights), 5-pin (lights + surge brakes), 6-pin (lights + electric brakes), and 7-pin (full-featured with brakes, power, and reverse).

Many standard light-duty trailers, such as many boat trailers and utility trailers, use a 4-way wiring harness to connect to the tow vehicle. This connection provides the required running lights, turn signals, and brake lights for the trailer. There is also an additional pin provided for a ground wire.. The right wiring depends on your electrical needs. To start, every trailer needs lights - brake lights, turn signals, and tail lights. Most also need side markers / running lights. Some have electric brakes, and some need auxiliary power.
