Vacuum valve?

Vacuum valve?
Does anyone know what this valve is supposed to do? It has two wires to it and a vacuum hose. But the hose is only about a foot long and then stops unplugged. The number on the side is EAC4100, when I search for that I find them for sale, but no descriptions of what it does. Its in the right rear of the engine bay.

I think that is the vacuum line to the vac reservoir, non-return valve. The vac reservoir is under that plate. It should be connected to the A bank vac spigot on the end of the inlet manifold. It may be joined by other vac lines.
It is certainly a vac line to something under that plate, anyway!

Mine had 2 of them, one was the dump solenoid unit for emissions junk, that was blocked off waaaay back.
The 2nd was the dump for the Cruise Bellows.
The Vac Advance Dump Valve had NO wires involved at all, just worked on differential vac on each side of a diaphragm.
I think???? I have a snap of it somewhere. If I find it I will come back.
There is another EAC4100 inside the cabin, on the LH side of the A/C assembly, and has somethong to do with recirc versus fresh aoir.
