Gauges: Replacing Bulbs

This is a relatively minor deal but I have some bulbs burned out on some of my gauges. I looked up under the dash and saw the biggest cluster of wires and didn't feel brave enough to tear into them without getting advise/help. How do you replace these bulbs? Where are they, etc.... HELP PLEASE!!!

I am going from experience with many different gauges. My boat is a 96 skeeter but....there should be a "plug" on the back of the gauge that unscrews (usually 1/4 turn) that is the socket/holder. Check and see if this is the case on your boat. I have to take a flashlight and stand on my head under the console to see mine.

did ya git er dun?
