There are two ways of installing the wiring to your vehicle

Universal wiring

  • The lowest price.

  • Bypass your vehicles electrical system.

  • Audible buzzer heard when the caravan, light board or trailer indicators are on.

  • Trailer Stability Program (TSP) not active if fitted to your vehicle.

  • Vehicle fog lights and parking sensors (if fitted to the vehicle) will not disable whilst towing.

  • On newer vehicles, the warranty may become invalid for parts affected by the towbar electrics. Please check with your vehicle dealer.

  • On newer vehicles with TSP, your insurance may be affected if you have an accident and the TSP could have prevented or reduced the damage. Please check with your insurance provider.

Dedicated vehicle-specific wiring

  • The most expensive.

  • Works in tandem with your vehicles electrical system.

  • Audible buzzer may be heard or a light may be seen on the dashboard when the caravan, light board or trailer indicators are activated.

  • Trailer Stability Program (TSP) activated if fitted to the vehicle.

  • Vehicle fog lights and parking sensors (if fitted to the vehicle) are disabled whilst towing.

  • On newer vehicles the warranty on parts affected by the towbar wiring is usually protected. Please check with your vehicle dealer.

  • Please note that your vehicle may require coding to enable some or all of the electrical functions to operate.

  • Not all vehicles will have dedicated electrical options available to them.
