I found them; Glow plug relays

After looking hi and low, I finally found the weakest part of a military vehicle (CUCVS and more). They were pricey at $30 (small price to pay when your thinking about blowing up your truck to generate some heat)but my friends and I never have to worry about being stuck somewhere without a relay. Beautiful

uh, they are a standard relay, you can get them at almost any auto parts store.\
just make sure that it is wired correctly inside, there are several different variations with the same outside housing.

ok, you've GOT to give some more detail on this one- it sounds awesome. What does "intake running crank it over" mean? You might have to use some more punctuation for us illiterate types
