Trailer, camper, and caravan wiring refers to the electrical systems that connect a towing vehicle (such as a car or truck) to a trailer, camper, trailer, or caravan. These wiring harnesses transmit electrical signals to power lights, turn signals, brakes, and other electronic devices on the trailer.

Well-made wiring is essential to ensure safety during transport, as it allows all lights and signalling systems to function correctly.

If you are looking to purchase wiring for trailers, campers or caravans, you may want to check that they are compatible with the type of trailer and vehicle you intend to use, and that they comply with European safety regulations.
