Mine is a 1200GS LC TB bought Sep 16. It is Euro 4 spec. The GPS plug, which was always taped up in the head-stock area of previous models, is now used to feed the GPS cradle. But there is another empty socket with a blanking plug tucked hard into a recess in the fairing on the right hand side. I've no idea what it's for. When I looked at other later bikes at the dealers I could not see the same socket, tho' I could not have a good poke about. It may well be there just a little too tucked away to spot. Unfortunately I was not on my bike so could not compare. The fairing recess is roughly opposite the Right fork leg. Have a good look, you may well have the same.
