Electric Brake Control Jumper Trailer Recommendations You must subtract your hitch loads from the Cargo Weight Rating (CWR). CWR is the maximum weight of the load your vehicle can carry. It doesn't include the weight of the people inside. But you can figure about 150 lbs. (68 kg) for each seat. The total cargo load must not be more than your vehicle's CWR. Weigh your vehicle with the trailer attached, so that you won't go over the GVWR or GAWR. If you are using a weight-distributing hitch, weigh the vehicle without the spring bars in place. 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. This harness may be included with your vehicle as part of the heavy-duty trailer wiring package. This harness is for an electric brake controller and includes a trailer battery feed fuse. It should be installed by your dealer or a qualified service center. For more information, see Towing a Trailer on page 4-53. 4-65
