The gauge cluster is easy to remove. There's 2 screws on top of the plastic bezel surrounding it, another screw behind the hazards button (pop it out with a flat head screw driver and un plug it.) Carefully pull the whole bezel out, it just snaps out. Un plug the clock if you have one.
The gauge cluster is exposed now. Take out the 4 screws, 2 on either side. Pull it out and unplug the connectors. Bring it somewhere to paint. Now you want the blubs with the brown bases, their's 7-9 I believe can't remember for sure. Lay them on some news paper and start coating them with the Krylon amber paint, you'll have to do one side at a time and once one side is done flip them over.
Installation is the opposate of removal. All the screws are a #2 Phillips. Good luck!
