Auto-rotor S/C vacuum lines
I am still uncertain about which vacuum actuators will go to which vacuum sources.
The TB has one timed signal (throttle place controlled) port and one constant signal port.
There is the manifold fitting on the left side of the supercharger.
There is the power brake tap.
The actuators that I find remaining are:
HVAC
Cruise control
Auto Trans modulator valve
Fuel pressure regulator
Fuel rail dampers (2)
evaporative control system valve
S/C bypass valve
ISV
Can someone list which actuators should see vacuum from which of these sources?
Feel free to ad to either list if you wish.....

This was OK except it doesn't identify which of the 2 throttle body taps he meant to feed the larger tree.
Also it doesn't specify the cruise control/HVAC source, although that could mean that you would use the OEM brake-booster tap.
There is no mention of the ISV source, although I suspect that it means to use the OEM source from the TB, but I don't know which one of the two that is.

The information you are looking for is in the WSM pages24-216,217.
The front vacuum tap is true manifold pressure and connects to the 5 way fitting at the rear of the engine. This in turn connects to:- fuel pressure regulator, 2 fuel pressure dampers, auto transmission vacuum modulator.
The rear vacuum tap is ported vacuum which is connected to the smog pump divertor valve.
The flappy valve solenoid and cruise control reservoir connect to a 4-way fitting at the brake booster.
