What wire do I need to find and tap into, in order to get my gauge to light up when I turn my headlights on?

 

Try running the wire to the fuse panel and piggybacking the fuse for the dashlights.

 

Or try going to your radio and tapping into the illumination wire in the factory harness. There are alot less wires to have to go thru to find it there. If you need the wire color behind the radio for illumination, let me know.

 

Where are you going to put the gauge? on the A-pillar or next to the radio?

 

Already done now, thanks though guys. No cuttin splicing needed. Found a wire that im assuming is for the fog lights and pluged in the wire. It's on the A-Pillar though.

 

Know that ugly **** of a bulb in the cubby under the center dash in front of the shifter? I took the bulb out and just spliced into that source. Its only on when the headlights or parking lights are on so it worked out perfectly

 

I did the samething.

 

cool ,w hat gauge pod did you get

 

Just the cup pod, and mounted it on my A-Pillar, Im going to get the CF A-Pillar with the dual pod eventually.
