The green wire can go under any convenient screw/bolt on the

Using an ohmmeter check the switch pins to see what gets
shorted together when turned on. I wo8uld assume that the like
labeled pins are a pair, but it doesn't hurt to double check.

This is not correct, or is at least misleading. The BLUE should get
shorted to the WHITE when the switch is engaged, and the BROWN should
get shorted to the BLACK. There should be a plastic ridge down the
center of the switch. Make sure that the BLUE and WHITE wires are on
one side of this ridge, and that the BROWN and BLACK wires are on the
other side.
