You can easily connect any type of trailer with electric brakes to a motorhome.
18-wheelers with air brakes tow trailers with brakes that are actuated by the alike air energy, using a take-off edge to the trailer brakes escape from the tractor unit's proficient cylinder. Regardless of the type of braking step a motorhome is equipped with, it Testament not be towing trailers with air brakes. Driving trailers and the other trailers a motorhome can legally tow own electrically-actuated brakes, thrown by a graduating charge to magnets inside the brake drums.8. Attach the brake controller connection, a blue 12-gauge wire, to terminal two.9. Attach the taillights/running lights/license plate connection, a brown 14-gauge wire, to terminal three.
1. Place the trailer's tow connexion cord, which Testament comprise seven conductors whether the trailer has brakes and four conductors provided it does not. Manufacturers normally operate a transitority attachment such as a plastic life tie to clout the cord to the underside of the towing Language. Typically the cord has a seven-pin connector pre-attached; whether so, plug it into the motorhome and include an assistant cooperation you research Everyone advantage separately.
2. Get a seven-pin connector, whether required. Conventionally the adult abbreviate of the connector Testament be attached to the motorhome so a female equivalent Testament be needed, however trial the motorhome tow parcel to confirm.
3. Trim the cord's outer wrap from the seven internal wires so that one and a half inches of Everyone internal wire's color-coded insulation is visible. Clinch no damage is done to the seperate color-coded insulators.
4. Application your wire strippers to remove half an inch of color-coded insulator from Everyone alone wire. Roll Everyone bared incision of wire between a finger and thumb to dream up seven tight and rope-like braids.
5. Remove the fastener holding the outer casing of the seven-way plug you purchased and pull the contingency elsewhere from the terminal hub it surrounds. Slide the example down the trailer's seven-core cable, exorbitant hole pointing toward the front of the trailer.
6. Attach your seven color-coded braids to the seven connections in the terminal hub. Each terminal's purpose and number will be embossed into the hub. There is a fastening screw at the top of each terminal; slip the braid through the hole below the fastener screw and tighten the screw downward into the hole until the braid is locked in place.
7. Attach the ground-to-vehicle connection, a white 10-gauge wire, to terminal one.
The by oneself alternative is a development called surge braking, which is not recommended by any motorhome or trailer manufacturer. Colossal motorhomes manufactured with air brakes in that the mid 1990s retain nearly universally been factory-equipped with a seven-pin trailer wiring harness.
Instructions
10. Attach the chassis battery connection, a black 10-gauge wire, to terminal four.
11. Attach the left turn/brake light connection, a yellow 14-gauge wire, to terminal five.
12. Attach the right turn/brake light wire connection, a green 14-gauge wire, to terminal six.
13. Attach the back-up lights connection, a purple 14-gauge wire, to terminal seven -- in the center.
14. Replace the connector case and the case fastener. Plug the connector into the motorhome and have an assistant help you test each function separately.
