Thanks for the suggestions fellas, but what would I ground to where and why? Engine to body? Alternator to engine? I currently am not having any ground issues at this point.

i ran grounds from main trans ground to top of alt and from top of alt to body, as trans to body grnd tends to go first.
Ah, I understand, I actually updated all of my grounds when I did my semi wire hide, battery relocation. I have some welding cable going from my - battery post to the bolt that holds the rear bumper on and another cable from the lateral bolt that holds the front bumper to the body to the bellhousing.
the main thing is to have the ground to engine/trans housing for glow plugs and starts/cold st. and a ground or 2 from motor to body. i ran a ground from trans tunnel to alt top, then another from alt top to body. it seems vw used 2 smaller ground wires to ground body to battery term. not 1 big wire.--that would be 1 connection, you indicate you have 2 body grounds, 2 smaller wires with separate connectors for each body ground. makes current able to flow more smoothly. as current is choosy and can get an attitude!
