Fuel gauge wiring question

You can also just clip and remove the black wire, and clip the metal spring with the contactor point and remove it, then leave the rest. You want the gage pointer to remain functional.

In the RTE instructions, it says to bend the limiter points out of the way, and their diagram does not show a black wire to cut, am I correct to assume that they are just using an old scrap gauge that doesnt have a wire for illustration purposes? Also, in your picture that shows the bundle of three wires, it does not show the ground attaching to the new ivr, so Im assuming that its just a ring terminal that goes under the mounting screw of the irv then to the ground on the circuit board?
As before, thanks for all the help!
