I'm getting ready to install my rebuilt tank. I removed the sending unit from the old leaky tank.

I am stumped on what wire goes where

One the top of the sender is an "S" and an "-" Ok, sender and neg

But look at the underside, the wires were sort of brittle from being in fuel for 20 years. I need to put those wires back with new connections.

I can see a connection on the side where the float rotates---is that a ground or to sender?

Next are two more wires, are those grounds?
This picture shows a connection. Am I right to assume that is a ground? Right above it on the surface it the "-" connection.

Now what are these two wires. Maybe one was tied off and I missed it when I pulled the unit from the old tank. Am I correct to assume that one of these wires (brown) goes to the terminal as stated above? "-" terminal.

Now look at this connections. I see two wires. One probably should go to the "S" but what about the other two?

I've losing it!

Is it possible those two brown wires need to be connected together, and the ground just grounds to the belly of the tank? I think logic wise, that is how this unit should work--but it has a bunch of excess wires

The unit in the background is the part that came out of the used tank that I had modified. It just just one wire. In the center of the outside metal portion, and grounds to the tank.

I haven't seen one with two terminals. Usually a pink wire to the sole terminal on top and a ground wire to a retaining screw.
