Help! With my V70 year 2003 the tank cover lock does not work, the lock has been removed and tested it works. Now there are two plugs in the trunk of the spare wheel, one is not used and with the other there are loud white cables coming from the direction of the fuse box, where with me 2 cables are loose, now I suspect it is the cables for the tank cover, but do not know where to plug them. Can someone please help me. Thanks Heinz
