depends if you have climate control or exec switches.
Depends on which thing you want to change it either has a standard bulb with a green condom over it or a layer of green on the back of the peice which requires light sanding to remove and if u sand to much it obviously goes through and removes the black and writing.
Your better off buying a replacement piece for it.
i got my Cluster face off this guy and it works well and he makes the shifter panel and aircon faces for exec fan stuff and he does custom work, you just need to ask him what you want, i got black cluster face with blue dials and a shifter panel that lights up blue with standard bulbs behind it.
so don't be put off by the fact that most of it is white in the pictures.
Its only bout $25 for an exec aircon panel.

If you have climate control then you need to remove a green sheet of film from under the screen and you need to be really careful, mine came out easy but 88greenvn broke 2 climate control screens trying to get it out, then soldur 1-5 leds to light the screen up.
