Hi,
Yes this is the same as my connector.
This tale harks back to family caravanning in the sixties, my Dad was very forgetful about the electric connection plug having
unhitched, I remember we once spent two days re wiring the plug without any instructions, the permutations were innumerable and we would get it all wired up and one light would n't work, over and over again. It was a very salutary lesson to me.
I now go through a litany in my head, hand break off, mover wound in, jockey wheel up, lx plugged in, check the lights, (fridge door and caravan door locked) gas turned off, spectacles , testicles, and when abroad ,drive on the right if you don't want sh*** etc etc etc.
Highmiler.
