if you remove the ash tray, there is a light above it that only lights up with the headlights, try tapping that wire... very nice install though!
I don't think that is entirely true. I think there is also a limit switch that it only lights up when the ash tray is open. I took my ashtray out and mounted my scan gage there. I had to disconnect the bulb cause it was always on.
I predict future happiness for Americans if they can prevent the government from wasting the labors of the people under the pretense of taking care of them.
