Lights flicker and gauge jumps around???

Do what you like, but when you do your own engineering, you're also on your own when things don't work as you expect.
Taking care of things and understanding how they are supposed to work is just too difficult, just spray a bunch of new at it, that'll fix EVERYTHING!
So are you saying that you have a bone stock all original car? You have never upgraded anything on your car? Everything is to factory specs? You must be busy on this forum if you critique every modification people make, engine builds, transmission swaps, rearend swaps, wiring, brakes, ect. People are always changing stuff to improve the reliability, performance, handling, and comfort of their cars. I swapped out the /6 for a 360, swapped the 904 auto for a 833 4 speed, swapped the 7.25 rear end for a 8.75, and rewired pretty much the entire damn car. You got anything you want to say about all of those upgrades I made?
