Towing a Trailer Trailer Brakes Honda requires that any trailer with a total trailer weight of 1,000 lbs (455 kg) or more have its own brakes. There are two common types of trailer brakes: surge and electric. Surge brakes are common for boat trailers, since the brakes will get wet. If you choose electric brakes, be sure they are electrically actuated. Do not attempt to tap into your vehicle's hydraulic system. No matter how successful it may seem, any attempt to attach trailer brakes to your vehicle's hydraulic system will lower braking effectiveness and create a potential hazard. See your trailer manufacturer for more information on installing electric brakes. A factory installed, 4-pin gray connector is located under the instrument panel near the top of the parking brake pedal. This connector has all of the circuits required to install most electric trailer brake controllers. A jumper harness to adapt your electric trailer brake controller to the vehicle is included with the optional Genuine Honda trailer hitch kit. To obtain a trailer hitch kit, see your dealer. Have a qualified mechanic install your trailer brake controller following the trailer brake controller manufacturer's instructions. Failure to properly install the trailer brake controller may increase the distance it takes for you to stop your vehicle when towing a trailer. Use this illustration to identify each terminal in the trailer brake controller connector. ELECTRIC BRAKE (BROWN/WHITE) BRAKE (20A) (BLUE) GROUND (BLACK) STOP (WHITE/BLACK) 212
