5-Way Connectors 5-Way connectors are available allowing the basic hookup of the three lighting functions (running, turn, and brake) and, besides the ground, one pin is available to provide support for another function. Typically the 5-Way Flat is used for trailers with surge brakes or hydraulic brakes. At a minimum, all trailers need at least 4 functions: Tail lights, Brake lights, Left & Right signals. 4 wires will give these functions, so the simplest scheme is a 4-pin connector. The most common 4 wire connector is the 4-Pin Flat Connector as shown here.

Use 12 gauge wire if your trailer has two or fewer braking axles and 10 gauge wire if your trailer has three or more braking axles. To wire trailer brakes, you will first need to determine the gauge of wire required. If your trailer has two or fewer braking axles, use a 12 gauge wire. 7-ways are some of the most common harnesses found on trailers. 7-ways provide the required running lights, turn signals, brake lights, and ground for the trailer. In addition, they provide three additional pins for a 12V hot lead, electric brakes, and reverse lights. Electric trailer brakes are a type of braking system that is specifically designed for trailers towed by vehicles. These brakes are used to slow down or completely stop the trailer when the towing vehicle applies brakes. They are an important safety feature that helps ensure the stability and control of the trailer while on the road. Want a brake controller with no installation?

Wiring Diagram For Trailer Brakes
Typically, a utility trailer wiring diagram will include the following components: a power source, a brake controller, a brake switch, brake lights, turn signals, and ground connections. The power source is usually the vehicle's battery, which provides the necessary electrical energy for the trailer's braking system. Connect the wiring harness. Plug one end of the wiring harness into the back of the brake controller. Then, route the other end of the harness towards the vehicle's 7-way trailer connector. Make sure to stay away from any hot or moving parts, and secure the wiring harness with zip ties or mounting clips as necessary.
The colors for a 4-pin trailer wiring diagram are: White: Ground wire. Brown: Tail/running lights. Yellow: Left turn/brake light. Green: Right turn/brake light. 18-gauge wire is the minimum recommended size for the 4-way plug. This should be used for the lights. If the trailer wiring is running down the left side of the trailer, then we splice the left side brake assemblies into the main electric brake power wire coming from the 7-way connector. We then run a jumper wire from the electric brake power wire to the right side brake assemblies (see photo).
