Legal requirements for becoming trailers with brakes vary community by authority.
Electric trailer brakes are actuated by an electronic brake controller fitted in the cab of the Motor lorry. The brake controller delivers a contemporary to electromagnets that deploy the brakes. Thanks to the happening delivered is proportional to the decelerating dynamism of the Motor lorry, the harder you brake the Motor lorry, the harder the trailer brakes deploy. The connexion between the trailer brakes and the Motor lorry occurs nailed down two of the wires in a round seven-pin hitch, the frosted wire to ground and the glum wire to the controller.
Instructions
1. Immobilize the trailer using revolve chocks. Uplift the trailer Language jack to lift the front of the trailer until the chassis is encircling even.
4. Route the loose white wire along the tongue to one of the front corners of the trailer, then continue along the frame rail to the first axle. Cut off the loose wire with wire cutters when it is adjacent to the wires exiting from the brake drum, trim away 1/2 inch of insulation with the wire strippers, then twist the two ends together. If the trailer has more than one axle, use the wire cutters to remove 1/2 inch of insulation from the cut end of the remaining loose wire and twist-join it with the wires joined previously in this step. Disinfected the wires remain Everyone revolve using a rag with household dish cleanser or mineral spirits, then seperate the chalky wire from the woebegone provided exigent. Remove 1/2 inch of insulation from Everyone wire using wire strippers.
3. Seperate the ghastly and blue wires from remainder of the seven-wire harness at the trailer side of the hitch. Disinfected the wires using abstergent or mineral spirits, then utilize the wire strippers to remove 1/2 inch of insulation from each extremely as 1/2 inch of insulation from the ends of 10-gauge loose white and 12-gauge loose blue wires. Twist the color-matched wires together between your forefinger and thumb to join them.
2. Recognize the trailer brake wires. They Testament typically Way out the constant brake drums behind of Everyone axle at the twelve-o'-clock position and be colour coded caucasian and unhappy. Use a soldering kit to solder the two- or three-way join, then insulate it with a shrink-wrap kit.
5. Bridge the loose white wire to the wires exiting from the brake hub of the next rearward axle, then repeat the joining process.
6. Continue the bridging procedure between each wheel hub until you have made a series connection to every brake on that side of the axle. Repeat the entire process, from trailer hitch to back axle, on the other side of the trailer, then use your soldering kit to solder the three-wire connection at the hitch and use your shrink-wrap kit to insulate the join.
7. Repeat the entire process with the blue wires so both wires of all axles connect to the hitch harness.
