Hi, I have the below tow bar and just need help deciphering the wiring.

I have two looms going to the left and towards the black box in the engine bay, and one red wire going to the rear drivers side light.

Any diagrams/instructions around?

Thanks!

That red wire looks like an after-thought.

Possibly a split charge wire for a caravan leisure battery. If done properly, it should be controlled via a relay.

Or perhaps a rear fog cut-out circuit...

The wire colours for the rear light clusters are...

This is the white barrel plug in the junction box.
T7/1 = Black / White for left indicator
 T7/2 = Black / Green for right indicator
 T7/3 = Black / Red for both brake lights
 T7/4 = Grey / White for the rear fog light
 T7/5 = Grey / Black for left tail light
 T7/6 = Grey / Red for right tail light
 T7/7 = Brown for chassis / earth for both rear clusters.

and then there is the separate black / blue wire for the reverse light.

There may be a mechanism on the rear fog light wire to prevent it lighting up when a caravan is hitched up.

If it was me, I would want to look inside the connector boots to see where the red wire actually goes.

Red wire goes to the rear left indicator, posted on another thread by accident!

Hoping I can get rid of it and use the main looms going from each of the tow sockets.
