What if you have a CA truck and have the Glow Plug Controller instead of the Glow Plug Relay? How would I go about testing this thing? It has 2 pigtail plugs goin into it...Thanks!

As far as I know, the GP Controller talks to the PCM and throw codes whenever it has a problem, so you best approach there would be to scan it with a good scan tool. You might be able to pull the GP harness off and monitor the GP pins on the harness (front two and back two) for voltage at first Key On similar to the GPR testing. I think the GP controller contains a series of solid state relays, one for each GP.
Sorry, don't have any direct experience with those animals.
