i jus ordered a boost gauge for my ae and the gauge works great and everything but w/e i do i cant get the light to work. i kno its not the bulb bcuz i put the + to the battery and grounded the neg, and it lite up. i was trying to get the 12 volts from the dimmer switch bcuz i only want to gauge lit up when i have the headlights on. when i try to connect the + to the dimmer i dont get anything, and i kno the ground is good. i kno that all my connects r good cuz of hooking it up strayt to the battery. i am getting the 12 volts at the dimmer but i cant get it to the gauge, when i connect it i get 0 volts. anyone kno what im going wrong or another way to hook up the lighting.
