Hello,
I can only find info on the Supercharged Vacuum lines. So a little help for the little old NA team please
The Break Booster I get its straight forward. I just want to know what to do with the three open ports Pictures in the image below.
I have a 1988 GT and it's the NA 3800 Series 3 automatic.

I need to know which port to connect to my fiero evap cannister next to the air filter. It has two toobs hanging from it.
And Should I connect any of thses ports together or block any off? The computer will not control the vapour solinoid I believe all I have to do is just hook it into one of the vacuum lines.

So in the image below I have a horizntal port on the left, a vertical on in the middle of the image and a plactic horzontal part on the right .

Thanks

Plastic to the right is the output of the Evap Purge Solenoid.

The port on the top of the manifold goes directly to the crankcase... Stock this will run to a tube that exists between the throttle blade and the maf sensor. This will not really be that easy for you to do... I would put a little filter or at least a hose that runs somewhere in the intake tube to this.

The other large vac port on the back of the TB is just vac. It normally connects to the series2 version of the black thing on the left. This port is commonly used for brake booster feed, but can be blocked off if needed.

The black thing on the right can be left alone.
