Wiring Kits

Our wiring kits come in various designs and sizes. Each one is specifically designed and developed to suit the given vehicle in regards to technology and connection systems. A number of features incorporated are:

Wiring harness designed to correct dimensions complete with towing socket and socket seal
Fixing pack including – screws, tie wraps, fuses, special sized cable grommet etc
An electronic trailer module or relay (where applicable. This will be suitably designed and developed around the vehicle technological requirements.
Installation manual

Trailer Modules

Modern vehicles have developed an ECU based indicator function. This means that the old style flasher unit no longer exists in these vehicles. In order for the driver to be notified of Trailer indicator failure, the trailer module is positioned in the harness and unlike the universal buzzer solutions, this will often be able to warn the driver of a flasher bulb failure on the trailer by activating a double flash frequency of the car indicators. This gives you the total confidence that, again unlike Universal electrics, an indicator bulb failure is monitored in ACCORDANCE WITH THE REQUIREMENTS OF TOWING LAW.

CAN-Bus modules we use in our wiring kits are also programmed to activate bulb failure systems and this can also incorporate the activation of a bulb warning symbol, bulb or even a text message within the driver instrument display.

Fog Lamp Cut-off

In the majority of cases, it is an advantage that the Right Connections towing kits are enabled with vehicle fog lamp cut-off as standard. This is a HUGE advantage for the motorist who happens to drive in foggy or low visibility conditions.

However, on a number of vehicle makes and models, this is not possible due to the technical system of these particular vehicles. Although it is not a legal requirement for vehicles in the UK to have cut-off enabled when towing, the glare reflected by the front of the caravan or trailer can extremely distracting, so whenever possible, we will ensure the vehicle rear fog lamp is deactivated when towing. Cut-off is either by mechanical means through the towing socket, an electrical method using a module, or the car is ‘programmed’ via diagnostics.

Mechanical – The fog light feed is broken with either a sprung loaded metal strip or a microswitch, which is housed inside the socket. The insertion of the plug into the socket creates the contact break.

Electrical – With this method, the contact is broken by the use of a relay which is prepared in the harness and breaks the circuit when it detects a fog light fitted on the trailer being switched on. The relay is mounted in the vehicle.

Diagnostically Coded – In most modern CAN-bus equipped vehicles the central electronics system is pre-coded at the factory to de-activate the rear fog. In some cases, this is not preset and so this needs to be re-coded using specialist diagnostic equipment. The vehicle detects when a trailer is plugged in and automatically cuts-off the fog light. (NOTE: UNIVERSAL ELECTRICS WILL NOT ALLOW THIS FUNCTION TO BE PERFORMED!)
