Interesting as it seems both sensor wires are Blue with a
Yellow
trace........as far as I can see.  They're pretty old and
cruddy,having not
been cleaned in almost 20 years I'm sure.

...The engine temperature to glowplug wire was probably blue
with white streak
Just yellow with age!
I'm missing this wire on my setup.
Now I see that post August '80 The coolant gauge wire became
blue/red streak and also linked to coolant shortage wire of
the same colour.
