Solenoids convert electomagnetism to mechanical motion - to open or close a
valve, for example. Solenoids are also used in relays to open or close
electrical contacts which act as an ON/OFF switch in an electrical circuit.

The glowplugs can be 10ga, no worries there, remember as somebody else said
its only 16a on a 4cyl. The one that really ought to be heavier is the wire
from the battery to the solenoid which has to carry the whole 80a. 10ga
seems to be adequate, in that its always worked for me but bigger is always
better right ;)
You can't get around 4 of those 10ga runs, gotta have one each to the
injectors.
A solenoid is a simple relay. 2 sets of contacts, one relatively low power
which activates the other higher power. I *think* all solenoids are relays
but not all relays are solenoids.

<<I think you're over stating how big the wire has to be in the heavy
section.>>
OK! Now I'm really confused! It sounded to me like you were saying 10 ga.
was not optimal for this circuitry:
<<I rebuilt with 10ga (I think) which is the biggest my crimper would
support. I have some much thicker wire (2ga?) but I've never gotten around
to making more cables.>>
Also, what I was trying to avoid with my idea was using 5 runs of heavy wire
versus one run of heavy wire.
BTW, is a solenoid the same as a relay???
