Subaru Forester: Connecting a trailer / Trailer lights

CAUTION

Direct splicing or other improper connection of trailer lights may damage your vehicle’s electrical system and cause a malfunction of your vehicle’s lighting system.

Connection of trailer lights to your vehicle’s electrical system requires modifications to the vehicle’s lighting circuit to increase its capacity and accommodate wiring changes. To ensure the trailer lights are connected properly, please consult your SUBARU dealer. Check for proper operation of the turn signals and the brake lights each time you connect a trailer to your vehicle.
