Product Information

Full details

The AB Tools TR405 3.5-metre trailer extension lead is an essential tool for drivers who need to bridge the gap between their vehicle's tow bar and a trailer equipped with a female socket. It is specifically designed for users operating trailers like Ifor Williams models that utilize 7-pin electrical configurations. While the 3.5-metre length provides generous slack for most towing setups, users should ensure that the cable is properly secured to avoid dragging or entanglement during transit.

Can I use this for a 13-pin socket?

Troubleshooting

Pros and Cons

Pros

  • Compatible with both 12v and 24v systems
  • High-impact, weather-resistant plastic casing
  • Tested and pre-assembled for convenience
  • Ideal length for standard towing distances

Cons

  • Fixed length may be too long for some compact trailers
  • Requires trailer to have a female socket connection
  • Heavy-duty casing adds slightly more weight to the cable

Setup, Compatibility & Care

To set up, simply insert the 7-pin male plugs into the female sockets on both your vehicle and your trailer until they lock into position. Ensure the pins are clean and free of debris to maintain a strong connection. Regarding compatibility, this lead is designed for standard 7-pin systems; check your vehicle's manual if you are unsure of your socket type. To extend the life of the cable, avoid bending it at extreme angles near the plug heads and ensure that it is not left on the ground where it could be crushed or snagged on road surfaces during operation.
