ELECTRIC BRAKE SYSTEM COMPONENTS. For these systems to operate properly, the trailer wiring end plug on the trailer must match the wiring pattern of the mating plug on the tow vehicle. The use of an electrical circuit tester is recommended to ensure proper match of vehicle’s wiring to the trailer’s wiring. On the way plugs the 12V wire and electric brake wire may be reversed to accommodate trailer (particularly horse trailers ). Bottom right: white wire , ground wire.

Attach the wire to the axle with zip ties. Various connectors are available from four to seven pins that allow for the transfer of power for the lighting as well as auxiliary functions such as an electric trailer brake controller, backup lights, or a 12V power supply for a winch or interior trailer lights.

Simply run it into the designated pin on the trailer plug and lock it in with the securing screw. Equipment trailers are a vital tool in the construction and landscaping trade. So having them working properly and being well-maintained is a critical part of business success.

The max amperage draw for the brake magnets on a single axle trailer (brakes ) would be 6. Route blue wires along the left and right sides of the trailer frame to the brakes. Complete Breakaway kits, Breakaway switches, in cab controllers, and electrical wiring and plugs are also available. Connect the brake ground wire at each wheel to the trailer frame. Transportation requires that trailers equipped with brakes have a trailer break away system for activation of the trailer brakes , in the event that the trailer should.

This requires a wire from the controller to the trailer brake. This is why some connectors have as many as seven pins, to make provisions for the multiple circuits. Route the black wire along the exterior frame into the engine compartment up to the battery avoiding areas that may pinch or break the wire k. Reconnect the vehicle’s Negative (-) battery cable and install the amp fuse into the fuse holder from step 7. Splice one blue wire of the Break-Away Switch to the electric brake wire coming from the trailer side connector (A - see diagram on next page).

Connect other blue wire of Break-Away Switch to the blue wire (labeled “Brake”) from the Break-Away box ( B ). The Blue wire goes no where near the brake pedal switch. Many styles of electric brake controllers are available that differ in how they look, and the number of brakes they can power, but all of them can be assigned to one of two main groups, Proportional Brake Controllers, or Time Delayed Brake Controllers.
