VW Electrical System Answers – Thank you Bug Me Video!
Since the last post, I have been frustrated at every turn while dealing with the combined projects of re-wiring and upgrading from the 6 volt to 12 volt system. Examining wiring diagrams from all over the net have been somewhat helpful, but never enough to complete the entire project.
As the second to last ditch effort, I dished out about $35 for the Bug Me Video on VW wiring. Within 30 minutes of watching the video, I was able to spot a number of connections that needed to be re-done, and at the same time, the video did a fantastic job of explaining how things worked together. Within the day, I was able to complete the re-wiring. The only remaining issue was the turn signal relay. The relay was one of the most frustrating issues, as the numbers on the relay did not match any of the diagrams, and the diagram on the relay itself wasn’t helpful. (i don’t read schematics.)
Finally, after using a cheap multimeter to track down the current, i saw that the power was getting to the relay, but not coming out. As i was moving around i tapped the lid, and the connection grounded, which caused the relay to start blinking. Of course! A ground! I dug through the electrical diagrams laying around, and found one on the bottom of the pile that showed a ground connection. 
The same diagram was laying around my garage, but without the ground info. All i can say is that the multimeter has become my best friend in this entire process.
