Cut the taillight plug from the taillight.

Strip the wiring back and join a resistor to the green wire from the taillight. Take the other end of the resistor and join it to the white wire from the taillight. 

Solder splice the white wire and resistor from the taillight to the white and black wire to the plug.

Solder splice the resistor and green wire from the taillight to the green and yellow wire from the plug. 

Solder splice the rest of the wires in the shown orientation. 

Cover the loom in plastic housing using electrical tape with the resistor sticking out. 

Your taillight has small arrows in the corner. The brake light should be at the bottom and the arrow facing outwards.

Feed the loom through the large hole in the bumper. 

If you have BSM's, fasten the BSM through the taillight bolts using the supplied flat and spring washers as well as the nuts. 

To fasten the rest of your BSM's, use M6x16 button heads and nylocs to bolt the BSM mounts up through the tray. 

Rivet the resistor to the tray using zinc small rivets.

Plug your taillights back in and fasten the looms to the tray using cable ties.
