Hi my car has a 13 pin socket and I'd like to convert my van to a 13 pin plug to match. Far superior to our 7 pin plugs in my opinion. Trouble is I cant seem to find anywhere that sells a 13 pin plug pre-wired with a few meters of cable (coily plug end even better) for the love of me! Any one know where I might find one? Otherwise I'll have to wait until I get on the continent! Thanks Andy P.
