SELECTING THE RIGHT TOWBAR ELECTRICS
Selecting the right towbar electrics is essential for compatibility and functionality. In the UK, you typically have three options:

Single 7-Pin (12N)
Ideal for basic towing needs, this socket powers trailer lights, including brake, indicator, and tail lights. It’s suitable for basic trailers but requires an adapter for caravans with a 13-pin system.

Twin 7-Pin (12N & 12S)
This system includes an extra grey socket to power internal caravan functions like the fridge and lights. Suitable for caravans built before 2008, it provides both exterior and interior power needs but has been largely replaced by the ISO 13-pin standard in newer models.

ISO 13-Pin
The modern standard combines the functions of the Twin 7-pin into one socket. It supports all lighting and internal functions for caravans built from 2008 onwards and is also used on some vehicles. This socket simplifies connections and ensures full functionality.
Choose based on your caravan’s age and your towing needs to ensure optimal performance.
CHOOSING THE RIGHT WIRING INSTALLATION METHOD
The next consideration is the wiring installation method. Older vehicles can use universal aftermarket wiring or vehicle-specific wiring. Newer vehicles often require vehicle-specific wiring to ensure all safety features are activated. Although more costly, vehicle-specific wiring integrates seamlessly with your car's systems, providing enhanced safety and convenience features like Trailer Stability Control. Universal wiring is a more budget-friendly option for older vehicles, offering basic functionality but without the added benefits of dedicated wiring.

UNIVERSAL AFTERMARKET WIRING: COST-EFFECTIVE AND PRACTICAL
Universal towbar wiring kits were once the standard for aftermarket installations. These kits bypass the vehicle's complex electrical systems, connecting directly to the car’s lighting functions. While cost-effective, they do not activate additional safety features, such as Trailer Stability Control, which are crucial for newer vehicles. If your car lacks advanced safety features or is older, universal wiring can be a practical choice, providing the essential lighting functions required for legal towing.
VEHICLE-SPECIFIC WIRING: TAILORED FOR MODERN VEHICLES
Vehicle-specific wiring, also known as ‘dedicated wiring looms’ or ‘plug-in kits,’ perfectly matches your vehicle’s advanced systems. This type of wiring is essential for modern cars, especially those under manufacturer warranty, as it maintains these warranties and activates crucial safety features such as Trailer Stability Control and parking aids. Our installation uses SP Diagnostic tools to programme your vehicle’s electronics, including brake systems, suspension, engine cooling, cruise control, and more, ensuring full integration and safety. This comprehensive approach guarantees that your towbar functions seamlessly with your vehicle’s built-in systems.

I had investigated a few tow bar fitting businesses in the Gloucester/Forest/Hereford area, and Vision was my preferred option, so I booked them to come and fit at my home in the Forest. The lead time was just a few days, and communications were excellent. Calum arrived very promptly on the appointed day, was very pleasant to deal with, and carried out a very professional job. The only addition to the quoted cost was a couple of mugs of coffee! Based on my experience, I would highly recommend it.
