16V Scirocco wiring guru needed...

[mr.utility at highstream.net (David Utley)]

Drew, 
  Thank you for the reply...  I am afraid I was not specific enough for you to 
help me...    Sorry...  :-(

  What I am trying to figure out is the nuts & bolts way to wire this harness 
so that it functions as it should...  There are four connections, and I am not 
sure where to begin to connect them...

Any ideas?

David
