- From the disconnected yellow valve there are two yellow vac lines that go to a connector at the firewall. Looks like 5 or 6 vac lines all connect here and go through the firewall. It's pretty dirty in there, but it looks like there may be one unconnected nipple in the middle of that connector. Hard to tell for sure though until I clean it up, and I don't see any stray lines nearby that look like they should go there.

OK, that one disconnected check valve goes to your door lock system. A coupe has another one, and the vac line is blue in color, I remember now.
I imagine there is a leak somewhere, and plugging off the door locks will remove said leak, and you can shut the engine off with the key.
The brown vac lines go to the starter switch.
