13 Pin Electrics

Doe's anyone else get frustrated when the 13 pin socket internal pins spin around causing them not to align with the socket and you spend ages trying to get them to line up so you can get them to fit into the socket on your car and be on your way..............arghhhhhh surely there must be a better design in the pipeline, until then any ideas on how to stop this happening, my caravan dealer tells me this is a common problem.

Thanks
