open the box , remove the knob (thin screwdriver) remove the nut and star washer
remove the nut for the test button
for the led bulb in center from backside spread the plastic open and pull bulb out , then pop out the bulb holder for the new plate
fit the component into the new plate
on the dash bezel you need to cut out some plastic for the controls to slide in (i remove OE the overlay first)
and youll need to remove some white plastic from bottom of the gauge cluster (use pliers and just twist off )
I secure the control wire into the dash bezel by gluing the wire into the crevice by the column ,
you can even drill a small hole on column side and use a ziptie there
