Trailer lighting ranges from primitive to sophisticated depending on the unit. The smallest trailers still require stop and turn lighting; a modern camping trailer may have side markers, reverse lights and separate turn signals.
The trailer wiring connections must be made by a competent automotive electrician. A poor or incorrect job can damage the lighting system or render it inoperative. Remember that when properly connected, the trailer lamps add electrical load to the car's lighting circuits; fuse ratings may need to be checked.
The 1991-95 Accord comes equipped with a pre-wired trailer connector. Look for it behind the access panel for the left tail light bulbs or in the spare tire compartment of the wagon.
Most trailers use combined stop, tail and turn signals (all red, one bulb). An electrical converter or adapter will be required to make the car lighting control the trailer lighting. These units are readily available at trailer or camping outlets. Install the unit according to the manufacturer's instructions.
