I've had mine on for almost 3 years, so I'll give you some tips...
-Since the hole in the gauges are too small, you're gonna have to cut it a little wider with a hobby knife.
-I know the wires are a little too thick, so you should sand the botton part of the clear plastic cover so that the wires will fit through.
-Use double side tape to stick the gauges on, fixes all the "needles get stuck on my gauges" problem.
*NOTE* Make sure you do NOT mess with the needles anymore than necessary. Doing so will throw the calibrations off, thus you will need new ones. EXPENSIVE
