Electrical grounds

[Scotto58]

Can anyone tell me exactly where the grounds are? Wiring diagrams show that there are ground but give any indication where they are. I want to check all the grounds and make any needed repairs/ changes preferably before I replace my taillights. Want to try to prevent any futher problems.
Thanks for any help you can give.

No telling how many there really are....grounds to frame usually near core support behind headlight area or fender mounting bolts, strap tied to transmission, strap from engine to firewall, strap tied to exhaust hanger, strap somewhere to fuel tank, ground near rear bumper mount from rear electrical..could be numerous more

Well, that gives me some starting points. Considering the issue with my right rear turn signal, I'll start in the back.

Thanks
