Glow Plug wiring diagram

Does anyone have a wiring diagram for the glow plugs? I think I have a short after the gp controller, but I'm having some serious trouble tracing the wiring.

Also, on a related note, can someone tell me where the glow plugs are located physically?

I should add that this truck does not have CA emissions.

Thanks!

Jason S.

if you pull the inner fender liner, you will see them. they are in the side of the head in the same general area as spark plugs on a gas motor.

on the drivers side there should be a wire on the front and rear glowplug and a rail from the front across each of them to the rear.

on the pass side i cant be sure if there is two wires or not. but there should be a wire and then the rail across the plugs.

Do you know if the rail sees ~12V when the glow plugs are operating? Thanks a ton!
