Also, don't bother trying to get the film off the back of the gauge faces. I tried doing that by sanding the film off and only did the tachometer before I gave up because 1) the speedometer needle wasn't coming off, and 2) it doesn't make much of a difference. The light shines through only marginally brighter. Save yourself the time & effort, and the fact that it's damn near impossible to get your tach needle back on accurately so it reads the exact RPM.
That sucks. I was about to try it myself but i was hoping it would be easier. Thanks for the info.

About the resistor wiring. Let me try to make this simple.

You have a Positive lead (wires coming off the LED bulb) and a Negative Lead.
1)The Proper Resistor is placed between your power source and the Positive Lead on the LED bulb.
2)The Negative Lead is connected to your Negative connection (opposite post from resistor).
3)If no resistor is used they will burn out very quickly.

4)Below are some rough examples of LEDs with resistors. You should always solder your connections for the best results.
