towing electrics intermittent

[jackdaww]

i ordered a nissan towbar with the new car order.

the dealer fitted a universal wiring kit ie NOT the dedicated vehicle specific kit. VSK

this was ok for a few hundred miles , then lost power to all caravan running lights.

the power returns after a few hours.

thinking the universal kit to be unsuitable, i had the right connections VSK fitted.

still had same problem except flashers and fog lights carry on working , just lose sides/stops.

has anyone experience or knowledge of this please?

thanks
