I have cleaned the 4 main grounding points inside the ZR1. I haven't had the ABS light come back on since doing this, but that dimming gauge thing still was happening. I will be cleaning the grounds when I pull the plenum in the upcoming weeks.

Pulling the plenum is a "right of passage" for ZR-1 owners!
It is incredible the amount of gremlins you can kill by R&R'ing those ground lugs at the back of the motor! Be sure too, to use some contact cleaner and a wire brush and get the lugs bright. then coat them with dielectric grease before replacing them on their posts. Be sure to clean the block where contact is made with the ground lugs as well. You might want to inspect the solenoid contacts on your starter while you have the plenum off - an excellent time to replace the posts and clean up the contact ring, as long as you're under there! Using a thin putty knife you may be able to slide it between the plenum and the gasket and keep the gasket intact. But, if not, Jerry's Gaskets has the ones you want. As others have mentioned, low voltage can cause a host of problems. Low voltage can be a bad battery, as mentioned, or corrosion of one or more of the battery terminals, or the alternator not charging properly. All of these can be checked at a Walmart car care center: they can load test the battery clean the terminals as needed, and also load test the alternator. couple all of these together, and I'd think you'd pretty well R&R'ed maybe 95% of the electrical stuff that will ever cause you issues.
