on my 2005 rrsport I have two tow bar sockets behind the rear bumper panel, will they have been fitted with the electrics or do they need connecting? I have searched the forum and I can find plenty of references to fitting the electrics but it does not mention fitting the sockets aswell? also will the 2010n model tow ball fit a 2005 model

Thanks in advance

PS if anyone has a second hand tow ball that they want to sell PM me  some of my Previous cars
