Trailer Wiring Harness The trailer wiring is a four-wire harness assembly. The wires are blunted and taped to the wiring harness. The harness and wiring are stored under the vehicle on the driver's side. The harness has no connector and should be wired by a qualified electrical technician. The technician can use the following color code chart when connecting the wiring harness to your trailer. Trailer Recommendations You must subtract your hitch load from the Cargo Weight Rating (CWR) for your vehicle. The CWR is the maximum weight of the load your vehicle can carry. The CWR does not include the weight of the people inside, but you can figure about 150 lbs (68 kg) for each seating position. The total cargo load must not be more than the vehicle's CWR. Make sure to weigh your vehicle with your trailer attached, so that you won't go over the GVWR or the GAWR. You'll get the best performance if you spread out the weight of your load the right way, and if you choose the correct hitch and trailer brakes. For more information, see Towing a Trailer on page 4-35 earlier in this section. Black: Ground wire. Yellow: Left turn lamps. Dark Green: Right turn lamps. Brown: Parking lamps. Securely attach the harness to the trailer, then tape or strap it to your vehicle's frame rail. Be sure you leave it loose enough so the wiring doesn't bend or break, but not so loose that it drags on the ground. Store the harness in its original place. Wrap the harness together and tie it neatly so it won't be damaged. 4-47
