Understanding the Wiring Color Codes

Before diving into the wiring color codes, it’s important to understand what they are and why they matter. Wiring color codes are a standard set of colors used to identify the wires in a trailer.

The standard wiring color codes for trailers are as follows:

2. What do I do if my trailer’s wiring color code is different?

If your trailer’s wiring color code is different from the standard color code, you’ll need to consult your trailer’s manual to determine the correct color code. Alternatively, you can use a multimeter to test each wire and identify its function.

The ground wire is white to help distinguish it from the other wires. It’s also a universal standard that makes it easy to identify the ground wire, no matter what type of trailer or vehicle you’re working with.

4. What’s the difference between a red and black wire for battery charge?

There’s no functional difference between a red and black wire for battery charge. Some trailers use a red wire, while others use a black wire. The important thing is to make sure that the wire is connected to the correct terminal on the battery.
