Universal towbar electrics

Universal Towbar Electrics

Universal towbar electrics are a cheaper alternative to dedicated electrics and are typically only suited for older vehicles where a dedicated kit is not available.

They connect directly to the vehicle’s rear lighting loom using tap connectors (Scotchloks). The signals are often passed through a bypass relay, which then sends them to the trailer socket to power the trailer’s lights.

Disadvantages of Universal Electrics

Compared to dedicated towbar electrics, universal systems have several drawbacks:

• ❌ May invalidate the vehicle warranty

• ❌ Hidden from the vehicle’s systems – no safety features such as trailer stability are enabled

• ❌ Invasive wiring that can damage the vehicle’s loom

• ❌ Less reliable and prone to faults

• ❌ Shorter lifespan – bypass relays contain moving parts that eventually wear out

• ❌ Lower quality – many universal kits are imported into the UK and made from cheap wires and plastics

🚫 For these reasons, we do not recommend or fit universal towing electrics.
