On the outside of the valve cover harness you will see a 9 pin connector, use the center (position 5) as the ground, ohm out the 4 at the ends of the plugs, so positions 1,2,8,9. Should all be less than 2 ohms.

Correct me if I'm wrong, but isn't that the pinout for the injectors, not the glow plugs?

Yes, IDM, not FICM. The point being we need to see at least 10.5 volts to fire the injectors.
