Hey, everyone - this is my first time posting and I don't know much about cars...just need a little help with what ought to be a simple installation.

I am installing an HHO system (http://www.watertogas.com) and I need to find an extra vacuum tube connection (preferably as close to the throttle body as possible.)

I haven't removed the coverplate from the Northstar, but when I do, I'd like to have some idea of what I'll find.

Any help would be great -

Thanks!
