Installing Indiglo Gauges

First, start out by removing the dash piece around the steering column (It's the piece that the ignition and dimmer knob is on.) It just pulls off and has a wiring harness attached to the back of it that needs to be unplugged. Then, take the curved piece off around the gauges. There are two screws on the bottom and two screws on the top. The top screws will require you to use a ratchet with a philips head bit in it or a short screwdriver, because a conventional screwdriver will be too long.

Next, unscrew the whole gauge cluster assembly. There are four screws that hold it in. Once the screws are out, you can move the gauge cluster around a bit. Now you need to reach around to the back of the gauge assembly and remove the three wire harneses, and then the gauge cluster will come out of the car's dash.

Now that you have the gauge assembly out, remove the two gold looking screws at the top of the assembly. Then remove the clear plastic cover and the black plastic gauge bezel. Before you can slide the gauges over the needles, you'll need to pop off the little black plastic covers that are on top of the needle. This involves prying the covers up with a screwdriver very carefully, because you don't want your needles to come off. Be absolutely certain that you don't take off your needles, because it will mess up your gauge cluster!

Now slide the indiglo gauges over the stock gauges by sliding it over the needle, then push it under the round part of the needle and slide the rest of it on. You'll want to put some double sided tape underneath the gauges so that they don't bubble up and cause your needles to stick, causing them to not function correctly. Once you're fairly certain that your gauges will not obstruct your needle movement, you need to put the needle caps, gauge bezel, and clear plastic cover back on.

Now you just need to wire the gauges to your car. As most indiglo gauges require a constant 12 volts to run, wiring the gauges to your dimmer switch is not a good idea, because the voltage from the dimmer wire fluctuates based on the position of the dimmer knob, which can cause your indiglo gauges not to work at all. Most indiglo gauges come with a switch to make them dim to your liking anyway.

I simply wired my +12 volts power wire from the gauges to my parking light fuse in the interior fuse panel, and then wired my ground wire to a good chassis ground. For the buttons that control the brightness and color of your gauges, I mounted them under the dash almost directly underneath the steering wheel with some double-sided tape. Now, simply turn on your lights and make sure that your gauges work.

Once you're sure that your indiglo gauges are working, install the gauge cluster back in the car, making sure to re-connect the dimmer switch harness. Then, go for a drive and make sure that your freshly-installed indiglo gauges don't obstruct the movement of your needles. Enjoy!
