buy a prewired trailer socket this shows wiring for socket all the same.if you get a £2 electric test 12v screwdriver remove panel to see back light wires on each side test with screwdriver to find out whats what.then connect to passenger side with scotch locks and run side light and flasher from drivers side across boot and connect up to warning bleeper and wire to socket and screw earth wire down to make good connection.
