I am installing my gauges tomorrow. Fuel pressure, EGT, tranny temp, and boost. I have watched every video on YouTube on the glow shift gauges. That's the brand I got. My question is in the directions it says I can get one of the wires I believe orange to be wired in to the headlight switch to turn lights off and on. How do I do that. Please help. I don't want these things to be on all the time. Which is what happens if I go with the same wire deal as the video. Tapping in to another switched color.
