Cig lighter, anything in the fuse box. Just put it on the dead side of the fuse socket (if that makes sense). So if there is a short it will still blow the fuse. Like if the stock is 10A then put the gauge on it and throw a 15A fuse in.

4 out 0f 5 of my gauges run from this wire. The other one, runs of my ECU. (AF Gauge). Works with no problems.

I used a test light and a needle to find my light source. Very easy and I didn't have to run a wire over to the cig lighter.

Turn your lights on and stick the pin through a wire under the dash. Check for power....if the light fails to come on, try a different wire. If the light comes on, turn your lights off to see if it's a switched power source or not. If it is, you're set. If the light stays on, try a different wire. I don't know which one I tapped into, but it works and it was very easy.

Good luck!!!!!

I just went ahead and ran it to the light that illuminates the cig lighter.

Thanks for all the suggestions!

I do not know where I got my 12v power. I have the wiring diagram for my car so I went from there. I believe I tapped the power that went to my turbo timer. Running water temp, oil pressure, and oil temp on that one. And for the rheostated power I just tapped the wire that came out of the back of the dimmer switch. And I have a switch that lets me turn off the lights on the gauges.

On my oil pressure gauge I put it somewhere unconventional. I placed the gauge on the door. Under the vent. Believe it or not....it is easy to see and looks neat. I only had to run two wires from the body to the door. The 12v rheostated power and signal wire. The power and ground i got from the door.
