Stealthram and vacuum lines
Just finishing up the install of the HSR on my 1991 Z28 . Im down to the upper rad hose and vacuum lines. I bought this system used and looked at Holleys instructions as to what fittings are neede and where theay are tapped. Everything looks like it was done correctly. I have 4 fittings on the back of the plenum. 2 large and 2 small. 1 large for the brake booster, 1 large for the PCV valve to the valve cover. Great. 1 small for the AFPR and 1 small for the MAP sensor. Great.
PROBLEM:
Im left with 2 vacuum lines. 1 for the heater controls (vents) and 1 3 way valve thing the I believe has to do with cruise control. What do I do with them? Can I plumb the heater control to the 3 way valve and add a port? How do you guys do it? Maybe someon can make me a little diagram...
Thanks
Kris

The heater control and cruise control vacuum line (if it is the one that goes to the cruise control vacuum storage canister) needs to have manifold vacuum, so you can T into any line you have there. That should take care of it.
