Coupling To The Tow Vehicle CONNECT THE ELECTRICAL CABLE – BUMPER PULL TRAILERS Connect the trailer lights to the tow vehicle's electrical system using trailer electrical cable. �� Check all lights for proper operation. Repair or replace non-working lights 63 before towing trailer. �� Check electric brakes for proper operation using brake controller mounted in the cab. ! WARNING Improper electrical connection between the tow vehicle and the trailer will result in inoperable lights and electric brakes, and can lead to collision. Before each tow: �� Check that all lights and turn signals work. �� Check that the electric brakes work by operating the brake controller inside the tow vehicle. ATTACH BREAKAWAY BRAKE LANYARD – BUMPER PULL TRAILERS If the coupler or hitch fails, a properly connected and working breakaway brake system will apply the brakes on the trailer. The safety chains will keep the tow vehicle attached and as the brakes are applied at the trailer’s axles, the trailer/tow vehicle combination will come to a controlled stop. �� Connect the lanyard to the tow vehicle so that the hydraulic actuator will engage or the electric brake pullpin will be pulled out before all of the slack in the safety chains is taken up. Do not connect the lanyard to a safety chain, hitch ball or hitch ball assembly. This would keep the breakaway brake system from operating when it is needed. Electric Breakaway Brake Lanyard
