Ignition Control Module problem

Ok now does the paint just have to be removed around the bolt hole? Or from behind the whole ECU box? Also the star washers do they go in between the box and the screw or between the box and the firewall? If I ground it with the NO 10 where do I attach it to on the ECU box?

Put a ring on the ground wire and attach it right with the ECU mounting bolts and star washer, so the washer edges bite into it as well as the ECU body metal.

The other end of the ground can be done the same way and mounted anywhere there is a solid attaching point.

I ground my stuff (like my regulator) to the power brake mount brackets, because that is physically where those types of parts are.
Anything like that would work well.
