Glow Plugs Don't Work

I have intermittent glow plug operation on a CGP30 with the Mitsu S4S engine.

My question is: Where is the time delay relay for the glow plugs (none shown in the wire schematic) and how are they reading temperature to tell the glow plugs to fire (in winter) or not (in summer). Nothing in the service manual.
