Guys, I installed my boost guage today, the only problem is that I dont know which color wire is the correct one to tap into the dimmer switch, if anybody can help me I would greatly appreciate it.

I can't remember the color....Take a test light and turn on the lights...back probe each wire til you find the one that dim's with the dimmer. (if I HAD to guess it's white with a yellow tracer on the switch itself....) I just did it 2 weeks ago and forgot already!!!http://www.dieselplace.com/forum/smileys/Ermm.gif

cool thanks. And this is the same from 03 to 04 I hope?

I would guess that it would be the same. If not sure, at least this would give you a good place to start using the test light to prove otherwise.

03 and 04 are the same.
