Trailer Breake Wireing Diagram. If you are rewiring your trailer completely. The following trailer wiring diagram(s) and explanations are a cross between an electrical schematic and wiring on a trailer.
This page has wire diagrams for many electric options including wires for trailer lights, brakes, alt power and connectors. I don't have a wiring diagram on me, so I don't know which of these translate into which wires in the back. This is for the trailer only.
Most trailer plugs are wired to suit very basic trailers, once you fit a brake controller the brake power wire is upgraded but the earth is left standard.
Referring to a wiring diagram for a trailer comes in handy during installation.
I need to know which wire the blue wire connects to, the white or black, assuming the other one goes to ground. If you are rewiring your trailer completely. This is for the trailer only.
