I Just broke one of the brittle vacuum nipples on the main Vac line to the brake booster.

I'm sooooooooo confused on this car. There's only one line coming off of the thick black Brake Booster line from the pump. I believe it goes to the key because when I broke the nipple there is now no shut-off.

If there's only the one nipple coming off, where do all the other lines get vacuum from???

Anyone got a link to a vac diagram?
Thanks,
Nick
