Check this link for a schematic.

hope this helps.
ps:
I like to read the previous note/comment on the same thread, so it's
fine with me to get a very long, multi comment message. As Al has
said, I REALLY prefer all new topics to be accurate. There are
bunches of threads that are just 'help' or 'newbe question' And I
try to add a comment if my reply is a reference like a link. It
makes it really really easy to go back and find a link in a bunch of
replys.
