I'm installing a gauge and need a good wire to tap into for the gauge lights. Should be a dimmed wire somewhere in the dashhttp://www.dieselplace.com/forum/smileys/Embarrased.gif. Anybody know where to find one?


Thx,


Jeff

You will find one at the light switch assembly....I forget the color...but am probably going to pull the dash today...if I remember I'll check.

It will be a brown wire w/white stripe. There will be one at every connector where ther is a light that dims. Here is where it is at the headlight switch.

How about at the illum. fuse? That's how I wired my Autometer gauges, and they dim with the factory switch.http://www.dieselplace.com/forum/smileys/Approve.gif

2003's and up don't have an ILLUM fuse.


Brn/Wht wire on the back of the headlight control module is the ticket for the new electrical system on the 2003+

GMCSID,


Thanks for the post. That is exactly what I was looking for. I need to find a good reference document for the truck. Does Helms Pubs have one out for it yet?


Thanks,
Dennis

I think the 01-02's it was the green wire.

The colors in the diagram above don't seem to match my truck. (04). I would assume that the pinout would be the same though.


Just a note....In my F350, I attached to a wire running into the steering wheel in the bundle ( it powered the buttons' lights). That might be a tad easier to get to than the headlight switch bundle athough both bundles are pretty easy to access. Anyone know which wire it is going into the wheel? http://www.dieselplace.com/forum/smileys/Ermm.gif
