Default Wiring Prosport gauge illumination to a fuse

I've had my boost gauge wired for illumination to the headlights since I first installed it about 6 months ago. It's been a constant problem, the connection keeps coming loose and then my gauge glows a weak amber, not white, until the headlights are switched on. So I've decided to tap the illumination wire directly to a fuse source. Which fuse should I use for it to glow white when headlights are off, and green when they are on? I was thinking the 10A ILLUM, can't remember which fuse # it is. Will this work?

Since the lighting system uses a switched ground to turn the lights on you may need to install a relay to supply power to the gauge. If the gauge has an isolated ground lead for the light then you should be able to tie that to the light switch and the power lead to a power source. When the light switch is turned then the ground will be made and the light will turn on.

Why not wire it to the stereo illumination wire? Its closer than your headlights. There is also an illumination wire going to your clock pod.

Was thinking about that too. Can you somehow point out which wires those are? Or even the colour? I think illumination to the stereo is purple?

Your easiest bet is going to be pull the clock pod as the plug going into the clock is labeled.
It should be labeled as ILL and the wire is most likely orange. Soldering would be the best connection method, or you could use a vampire tap for something easier but still rather secure.

The violet wire for the illumination system is tied to the hot side of the circuit. The orange is tied to the controlled ground side. Do not tie to the orange wire or you will have illumination problems.
