Universal Wiring

Universal wiring is usually the cheapest type of towbar wiring fitted to vehicles. This is where we hard wire to your vehicle's existing wiring loom and connect the socket to your vehicle using special control relays if required.

If your vehicle is covered by a manufacturer's warranty, we recommend you do not fit this type of wiring as it can invalidate the manufacturer's warranty.

Vehicle Specific Wiring

Leicester Towbars recommends vehicle specific wiring for almost all new modern cars.

Vehicle specific wiring connects to your vehicle using the same installation points as the manufacturer, meaning that it does not effect the manufacturer's warranty.

Most vehicles communicate using the vehicles gateway (CAN Network). Some vehicles also have towing safety functions programmed in their preinstalled software, which just needs activating using our coding equipment.
