I've got the question once or twice, about how hard it was it install/wire my gauges. So here's the quick and dirty for anyone interested.
They are the Prosport 60mm Amber/White Electronic gauges...purchased from Pricematchedparts.com.
You WILL have to remove the dash...which requires you to first remove the center floor console. The how-to's I followed are
here and
here respectively.
Now, with that done, you have something that looks like this:
Now on to the install. Take off all of the HVAC plumbing that's stopping you from accessing the center gauges and pull them out. (While your at it, there's no better time to replace your cracked dash vents

) How-To's
here and
here.
Now that you've got the gauge cluster out, dissassemble it. The black bezel is the piece your after. What you're going to do is cut out the inside so that it looks like this:

A dremel is probably ideal...but i used pliers and a pocket knife because i'm gangster...and dont have a dremel.

DONT GET CARRIED AWAY when trimming! You want the back, smaller part of the gauges to fit in as snugly as possible. This is one of the main things that keeps the gauges from rattling around or spinning.
Next, put the gauges through the front side of the dash where you want them, and slip the modified bezel over the back of them just about an inch, leave some play. Turn the gauges so that they are as close to the correct orientation as you can get, then push the bezel on the rest of the way. If you cut your bezel nice and tight, the dash should now be pretty securely sandwitched between the wide part of the gauges and the bezel.

Again, check the orientation. You want it as close as possible. You will be able to turn them once the dash is mounted by reaching through the vent hole right below them, but once you get the brackets on in the next step, it's much more difficult.
Now, to make sure everything stays nice and snug, use the bracket that comes with the gauges to secure the bezel in position. The bracket will need to be cut to length. (careful not to cut it to short. Better to be a bit long than a bit short)

Some of them need to be left a bit long, so you can spread them out, because the bezel has holes in some spots.
Hard part done. Now just the wiring.
I ran all my wires down behind the knee protector where the connections would be much easier to access. You dont want to have to pull the dash back off if you find something's not hooked up right, or you decide to change the way they illuminate.
From here, just follow the wiring guide that the gauges come with.
Take your time, do it once, do it right! You really dont want to have to pull the dash back off to fix something!
