4AGZE gurus please help...

Just need to sort out some of the bag of problems I have run into recently.
- I read that the SC ventilation system can be bypassed by connecting two metal pipes at the ends of the SC with a piece of hose without damaging the system. Otherwise how should the control switch be controlled? (aftermarket ECU) Anyone had experience with this?
- My motor is Map sensed and there are three pipes protruding from the intake just before the throttle body. One is cam cover breather, another is the SC ventilation line, but the third is a mystery. What is it?
- Is the alternator (AE92 or 101) internally regulated?
And does anyone have access to a diagram of the vacuum lines for the engine? Lots of mine are cut.
Thanks for any help.

if yr supercharger is on at idle it will suck yr pipes in badly
i think
if u have aftermarket ecu then use the auxilary output to trigger a relay to then turn on the supercharger clutch
the std ecu turns this on somewhere around 1500 revs
the thrid pipe gos to a/c idle up
plug it if u r not runnig a/c

another way to do it is to get an msd rpm activated switch
get this to turn a relay on at a desired rpm

I think the idea is to turn on the blower at a given RPM AND load, not just RPM. Also, the alternator is internally regulated, there should be a plug with 3 wires on it, as well as the main wire back to the battery. The three wires are for Field, Sense and the warning light.

Thanks all for the advice.
I was originally asking about bridging the SC ventilation lines. The small diameter rubber hoses which go to the seals at each end of the SC unit. These are connected to a valve or soenoid which is controlled by the ECU. I dont have the stock ECU, so I dont know how to control it. I had read that this valve/solenoid could simply be bypassed and removed, saving me the effort of sorting it out and freeing up an auxilliary output.
I plan to run the SC clutch off a combination of throttle position and manifold pressure and maybe RPM. Not up to that yet though.

i don't know if gze's are the same but on ge's there is a vacuum line that goes to the fuel pressure regulator and i think one goes to the carbon canister, not sure on that one though.
