Hello! I recently got my first car! It's a 96 Celica. I also got some glow gauges for it, and they are very similar to the ones shown up this page. What I cannot figure out though is how to find a power source. They say that they need a 12 volt power source. Should I run wires connected directly to the battery? Also, they come with a dimmer can color changing switch. Can I somehow get rid of my old dimmer switch and use the wiring from that to power and control my new gauges? PLEASE HELP! THANKS!
