It seems you have wires in the correct locations, with the ground going to the screw on the outside and the signal wire going to the center terminal.

what is the other spade for?

It could be for some other application. It looks like your sending unit has been changed at some point. The original had a screw connection instead of the spade.

Ignore the "reducer" note. That was for another post.

I would. I did on mine. My instrument lights got brighter telling me that I had voltage drop that went away by giving the back of the gauge cluster a good or in my case a better ground.
