Where are all the grounds on a KL-DE in a 1999 626

I jut picked up a 1999 626 and it's having some electrical issues and I'd like to start by cleaning up all the grounds, The battery posts are seriously corroded and if the other grounds are that bad it would cause problems for sure!

Basically you're driving along and the internal lights and headlights will quickly blink on and off, the engine will also sometimes miss, usually just once. This happens mostly on rough roads, so it seems like a short or a bad ground.
