dimming wire for gauge install
I've tried searching different combinations of keywords and I've come up with nothing.
I'm looking for which wire I can tap into to dim my gauges when my headlights are on. Can anybody help me out? And how do I power gauges from an empty slot in the fuse box?

When you turn your lights ON, theres 3 positions on the light wand. OFF, Parking Lights and Headlights. Since you have a 97 you may have a 4th, DRL-Daytime Running Lights.
I re-read your post. U wanted to wire it to the headlights, you have to find a wire diagram for the headlight circuit. What I did was easier.
All I did was hooked up my DVOM(ground the black and the red goes to testing wire) to the cigarette lighters circuit. I beleive theres 3 wires to this circuit-Ground, Power to Lighter and Illumination Light. Turn the Parking Lights ON and check for Voltage(should read 5V IIRC, turn OFF parking lights the voltage should be near zero/0.
You found your light source to your gauges. You use the cars Light dimmer to dim the gauges.

You want to use a 12V switch for this, hence "Parking Lights". If you use a constant 12V your gauges will be lit constantly unless you hook up a switch which is a waste of time and a switch.
Here are some pics of how I did mine, I have a Boost gauge and Oil pressure gauge mounted where the cigarette lighter was.
Theres a 4 wire blue plug for the cigarette lighter, I only used 2 wires from this-Blue/Red and Green/Orange
I used the Green/Orange wire for the White wires from to the Gauges bulbs. The Blue/Red wire went to my oil pressure Gauges "I" prong-theres 3 prongs in back of this gauge-Ground, signal and "I".
