I noticed you have a 2003 as well. What fuse or what wire can I tap to illuminate my boost and EGT gauges?? I cannot find a fuse labeled anything that would make sense. It's the last thing to do with my gauge install. So far so good, but holding the 12V in the cigarette lighter when I drive down the road isn't very easy! Hey, what can I say....had to try out the gauges!





Thanks a bunch!

Minn, I tapped into headlight switch to get my illumination, find the one that controls the interior lights and your golden. Hook a test lamp up and see which one gets bright/dim with the dimmer. I cant remember the color at this piont to save my life, sorry.

Hmmm. I pulled out the headlight controller assembly from the dash, but it all comes out as a unit and a big ol' wire harness coming out the back of it.

Its the brown wire with the white stripe for gauge illumination, that will also function with your dimmer
