Towbar electrics sorted
Thanks to trial and error and one blown 5amp fuse,I have now sorted the wiring.Wiring to tow socket is normal with the exeption bieng the red is Renault pink.
The purple to fog light cut off.
You take the connector plug from the light cluster and attatch it with circuit biscuit,face to face with with the connector with single blue wire from tow wiring loom.
The second connector on towing loom goes into the rear light cluster.
I can understand why the fog lights cut out if towing a caravan(If its cos of glare?).But if towing a small trailer I cant see the point especially as most small pre built trailers only have one rear fog on the offside?
