Vehicle Specific Wiring
Each kit is designed specifically for the vehicle that it is fitted to, and rather than soldering or using ‘Scotch Locks’ to connect the towbar wiring, which is the case with universal aftermarket wiring, these kits interface with the vehicle systems in the same way as the vehicle manufacturer intended.
Due to the complex nature of dedicated wiring it is inevitable that is more expensive than universal wiring. This cost is anywhere between £50 and £300 more depending on the vehicle. Although in most cases the additional cost is less than £150.
The extra cost is justified because the wiring is installed as the vehicle manufacturer intended it to be fitted, it means that your warranty won’t be affected. If your vehicle is less than 3 years old, or is still within the manufacturers warranty, you would need vehicle specific wiring to protect that warranty.
The wiring is designed to work with the vehicles on-board systems, certain functions on the vehicle are activated that would otherwise not work with universal electrics. Some of these features are vital safety features such as Trailer Stability Control, and other convenience features such as the cut off of your fog light and parking aids while towing.
