Looking at a picture of the back of the fuel gauge on another thread, I'm not sure which wire goes where. The wiring diagram I have makes it look like the hot wire from the ignition goes to the full side of the gauge, the side closest to the ignition and the sender wire goes to the empty side. That is the way mine is hooked up. I saw another thread where the hot wire was hooked to the empty side and the sender wire was hooked to the full side. I tried this on mine and I get no flicker, nothing at all. I would like to know which way is correct, though.
