Advice - Broken Wires on GU Nissan Patrol

A piece of advice that may prevent some grief.

During a recent trip including lengthy severe corrugations, two wires to the rear lights on my GU Patrol severed (one wire on each side).

The failure occurred with the added Nissan loom for the trailer plug. This loom is fitted by separating the original plug/socket connections and joining the trailer wiring loom in between with matching plugs and sockets. In doing so means there is extra length in the loom which in my case was not supported or secured.

The failure was caused by excessive up and down flexing at the plug/socket causing a ‘mechanical’ break of the wires. The wires broke at the cable entry at the backs of the plastic plug/socket connections which meant the wires could not be rejoined.

So a suggestion. Check the wiring and plug/sockets behind the rear lights in the bumper and secure excessive movement to prevent flexing at the plugs/sockets.

My local Nissan dealer has taken an interest in the failure and indicated they would notify Nissan HQ. The trailer plug wiring loom was replaced under warranty without question.
