Vacuum Hose Diagram

Hi! Does anyone have the vacuum diagram for the m103 engine? I've used search but all I've come across is one for the m104 engine. I have a line disconnected and broken but have no idea where it's supposed to be attached. Thanks!

It starts somewhere in the passenger side fender, and follows the path with another vacuum line that connects to a thermostat looking object on the exhaust. The one that broke off lead somewhere towards the airbox however I cannot seem to locate anything missing or not connected. I asked about this in another thread but couldn't find what the person was saying. Hence why I would love to locate a vacuum diagram.

It connects to the breather hose that is attached to the air cleaner.

I was under the impression that connected to a y split, that had the other line going to the fuel pressure regulator.

If it doesn't then what would this connect to?
