Fuel gauge wiring question

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!
Yes, I just attach the black IVR wire to the circuit board grounding screw. They must have used a scrap gage. That black wire inside the gage is the 12V feeding the points IVR. You can just bend the points on the wire wrapped bi metal spring out of the way, but I clipped the black wire and removed the vibrating point regulator, left the gage side intact.
