Types of Wiring
Standard (Generic/Universal) Wiring:
This is the traditional norm for towing electrics, it works by taking a small current signal from the vehicle’s lights to trigger a relay and send a direct power supply to the towing socket. It does not communicate with the vehicle and will not activate any safety or convenience systems. It does however isolate the trailer wiring from that of the towing vehicle, thus protecting the car’s wiring from damage should the wiring in the trailer (or cycle carrier) malfunction. It is a tried and tested system in very wide use. Bypass systems are found both in “universal/generic” (non vehicle-dedicated) systems and in dedicated and OEM (original equipment manufacturer) systems. Standard wiring is almost always the cheapest option, and often by a significant margin.
Dedicated (Vehicle Specific) Wiring:
For most vehicles standard wiring is the preferred choice given the higher cost of dedicated, however for many vehicles it is advisable to choose the latter. These include:
1. Vehicles with advanced towing/safety features e.g. TSP* or ACC** (see explanation below);
2. Vehicles still under warranty (check whether your warranty provider specifies a dedicated wiring requirement);
Please note: With dedicated wiring some vehicles will require re-coding at the dealer in order to activate TSP and PDC/Fog light cut-off – in the vast majority of cases we can do this here.
* Trailer Stability Program (to help reduce the ‘snaking’ tendency of a trailer).
** Adaptive Cruise Control (increases breaking distance between vehicles when towing).
