Some models of the vehicle are equipped with a junction box for connecting the trailer wiring. The box is located in the trunk of the vehicle near the right combination lamp. The illustration shows the color coding of the electrical wires that go to the junction box and the purpose of the individual terminals on the box. Since the wiring on different brands of trailers may differ, contact a trailer electrical specialist to check and, if necessary, match the wiring between the trailer and vehicle junction boxes. In some cases, it may be necessary to install an adapter electrical box.
