My dash light dimmer has three wires, a hot, a ground and a variable output(hot). I put two after market gauges in my console and for these gauge lights, I tapped into the variable wire at the dimmer. When these lights are on, the dash lights are off and vice-versa. In other words the lights in the new gauges dim in the opposite direction to the dash lights. I then checked the dimmer output with a tester (simple bulb and ground). The same occured with the tester. When the dash lights are dim, the tester is bright and vice-versa.

What am I missing here? How do I get the new gauge lights to go dim and bright with my dash lights?
