Question what is this gizmo?

This gizmo on my '88 7.3 IDI started smoking the other day and blew the glow plug fuse, so I chucked it out and now I wish I hadn't because the cold timing advance doesn't kick in and starting is kind of hard. It said Eaton Controls on it. Does ANYONE know

(1) what it is called?
(2) what does it do? Control cold timing?
(3) where can I get another one?

Basically this thing is a hockey puck with a cable plugged on the side and a single vacuum hose on the flat side that goes to the IP. It's near the fuel filter tower on the right wheel well. It seems to be for opening/closing a vacuum line which I think is connected to the cold timing advance on the IP. Mainly I just need another one, or some alternative solution.
