As I am putting things back together I realized i should have been more perceptive when I pulled everything apart. My issue right now are the battery power and ground cables. If I can get some help of what goes where that would be great. Pictures would be AWESOME!

This is what I know so far, please correct anything, I know I am missing something:

Positive:
Battery to starter
starter to jump start lead
Starter to alternator
Alternator to post under bulkhead connectors


Negative:
Battery to passenger side bell housing bolt
Lower crankcase to passenger side motor mount

Factory configuration:

Positive:
4 gauge Red from battery to starter
4 gauge Red from starter to jump start post
Bundle of Browns from starter to alternator
Bundle of Browns from alternator to bulkhead bolt

Negative:
4 gauge Black from battery to TAB bracket
Braided strap across motor mount
6 gauge black from frame under coolant expansion tank to bulkhead bolt
This from bulkhead bolt forward:
773

Some owners have substituted battery cables for the Brown bundles.

Some owners augment the braided strap with an additional block ground (usually made from battery cable).

I made a short little pigtail to relocate everything originally attached to the starter motor to a junction several inches away (makes it much easier to work with the starter motor):

Thank you very much sir! This helps out enormously. Even have the wire thicknesses!

If you still wanted/needed pics of any specific areas, just let me know. My car's electrical is 100% stock/OEM (other than a FanZilla, LockZilla, and RemoteZilla) and could be used as a reference.

Thanks Josh, but Bills list is all the description I need. I am very familiar with the car at this point, haha.

Definitely something I'd do - especially if I had everything apart!

Thanks for the link Bill. I may do this in the future if I see issues with my grounds. I just redid the front end harness last weekend. Cut back the wires and soldered on new grounds, and updated some of the connections to weather-pack. Just a little warm up for the engine wiring I have to do!
