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.

In May 2023, a Belgian Malinois named Wilson played a key role in the rescue of four children lost in the Amazon jungle. The young children were missing for 40 days after a plane crash that killed their mother and other adults. Wilson tracked the children's footprints, leading the military to their location.
