I have a 2L diesel that I'm putting in my 4runner. Originally came out of Canadian 84 2WD Pickup. There is a fuel heater on the fuel filter assembly. As I am doing all the wiring myself, I am curious how the heater worked and how I should wire it. Does it turn on while running, or before starting? Think I could even leave it on overnight or would it just burn out?

Pic? The factory HDJ fuel heaters work on vacuum - thick fuel increases vacuum in the fuel lines and pulls contacts together in the fuel heater to warm the fuel. Heater receives switched power.
