In a trailer plug, the ground wire is always white and it is also referred to as the “ground pin.” The rest of the wires vary in color and function based on the configuration and purpose. A typical 7-way RV blade format is used for travel trailers and campers, which use a SAE configuration. Different types of trailers use different plug types, so it’s important to know what each wire does.
The first four connectors are red, yellow, and blue, but they don’t have to be connected all the time. Depending on the size of your trailer, you may only need the first four wires. The unconnected pins are harmless, but they might not affect the performance of the trailer. If you don’t have brakes or auxiliary power, you can leave the blank spots unplugged. However, if you have a large vehicle that requires all 7 wires, you’ll need them all.
The second connector is used for the lights. It should be large enough to connect the lights to the trailer. The lights must be waterproof and be rated for at least 100 watts. A trailer wiring diagram can help you decide which wires you need and how to connect them. You can also choose to install central trailer lights, which may not be needed. The last connector, on the other hand, requires a specialized trailer wiring harness.
What is the Color Code For Trailer Wiring?
To make connections easy, trailer wiring is standardized in color. This way, you’ll know exactly which wires are connected to which other components. Here’s a list of the typical trailer wire colors and how to determine which one to use. When connecting your trailer’s lights, be sure to match the wires’ color to their function. For example, white means ground, brown indicates a taillight, and green means right and left turn signal lights. Blue means hydraulic release or electric breaks. Red is for 12V power and auxiliary.
Red wire is the ground wire. If your trailer has a central light, make sure to use brown wire for that. If not, you’ll have a hazard. For the lights on the trailer, choose the appropriate brown wire color. The wire’s color must match the power needs of your lights. Utility trailers may have a small brown wire, while larger enclosed trailers may need a bigger one.

In addition to the white and black wires, you’ll find a red wire on the 7-core connector. The red wire is responsible for the auxiliary power of the trailer, and it also provides access to the positive power from your vehicle.

Also, be sure that your trailer’s frame is grounded. You can do this by ensuring that the trailer’s grounding connection is good.
You can also identify the lights by their color. Trailers usually have white, black, and green wires. The white wire is the ground wire. The green wire is the turn signal wire. Finally, the black wire connects the running light to the brake light. A white wire is also used for the tail light. When wiring a trailer, remember that there are two types of wiring.
