Switched light source location?

[str5010]

I have a guage I am trying to wire up and I need to know where I can find a wire in the fuse block in the driver's side of the dash that is a switched light wire. I need to hook up the dimmer wire on the gauge so when I turn on the headlights at night the gauge won't be so bright, but I'm not sure which one of those wires will do this. I tried to find other threads about it on here but the only others I found didn't have any answers. Thanks for any help.

Look in the How To section for the UEGO install. It gives you a wire to splice into the back.. but it wont dim.. its an Acc pwr.

I dont quite understand. It talks about splicing into the wiper wire for power but I am not looking for just gauge power. I have that done already, Im just looking for a wire like the one in the middle of the dash that runs to the boost gauge that only turns on when the lights are on so I can hook up the dimmer function on the guage. After reading that how to I was quite suprised to see the correction that was made to it about not splicing into the black wiper wire for power because of a potential fire hazard. I have a bunch of my stuff sliced into that wire and it has been that way for 2 years now. Thanks for the help though. Any other ides on which wire in that fuse block might work for the dimmer?
