8-50 Driving and Operating Trailer Brakes Does the trailer have its own brakes? Be sure to read and follow the instructions for the trailer brakes so they are installed, adjusted and maintained properly. Because the vehicle has anti-lock brakes, do not tap into the vehicle's brake system. If you do, both brake systems will not work well, or at all. Conversions and Add-Ons Add-On Electrical Equipment Notice: Do not add anything electrical to the vehicle unless you check with your dealer/retailer first. Some electrical equipment can damage the vehicle and the damage would not be covered by the vehicle's warranty. Some add-on electrical equipment can keep other components from working as they should. Add-on equipment can drain the vehicle battery, even if the vehicle is not operating. The vehicle has an airbag system. Before attempting to add anything electrical to the vehicle, see Servicing the Airbag-Equipped Vehicle on page 2-34. Trailer Wiring Harness All of the electrical circuits required for the trailer lighting system can be accessed at the driver's side rear lamp connector. This connector is located under the carpet at the rear corner of the cargo compartment.
