Not much to it really
See the Chassis Service Manual available for free via

wildaboutcars.com

carb or manifold to distributor.

IF you want/ need it then the Thermal Vacuum Switch on the intake is labelled
D distributor
C Carb
MT manifold tap.

Big one to power brakes if applicable.
Bigger one to PCV in LH valve cover.

One MT to auto trans if applicable

that's about it.

  1. A/C system
  2. Air cleaner valve
  3. Transmission modulator

There really aren't very many lines.
