TD Wiring Question

[Robert J Donahue/DELCO <RJDONAHU@mail.delcoelect.com>]

Does the speedometer cable, starter cable, 12V battery lines,
and horn wires all go through the same one inch hole on the 
right hand side of the firewall (right next to the horn)?

I'm getting ready to re-wire my TD and the DPO has made so
many modifications (or should I say kluges) that I can't tell
where things go. Murphy's law says that any pictures I look
up in the books will not show the detail I need. I would give
my right arm for a good picture of the underside of the 
dashboard.
