Can anyone confirm now many wires goes into the holder for the dual filament bulb holder? I opened mine yesterday and it only has two.
 

there are three wires in the socket/holder-one for ground,one for tail and one for stop
 
you can use a stop/tail socket from an early revision,just use a knife to trim the plastic lock tabs to fit the later kouki lights
 
chop the two wire socket off and solder/heatshrink the tail and ground wires from the new socket (three wire) to the correct wires
then the remaining wire (3 wire socket) goes to the brake light wire on the one next door
