Fuel sender connections:

Looking at the sender connector on top of the tank, up is towards the front of the car, the connectors are 1, 2, 3, 4 left to right, top to bottom (1 is upper left, 2 is upper right, 3 is lower left). The connections are green 1, black 2, brown 3. I suspect this means: 2 to +12, 1 to gauge, 3 to gauge light, but I haven't verified that, yet.
