On the back of the instrument there are labelled connections:
S - this comes from the center screw of the fuel sender (Stewart Warner on my old RV-8)
I - this is 12VDC in
G - this comes from the sender ground: I used one of the screws holding the sender to the tank access plate with a ring terminal
The two wires at the top are for instrument backlighting. I had these going to a dimmer pot.
