Federal Emissions..
Expert:  GM Tech (Cam) replied 4 years ago.

Below is the GM diagram. Of the studs, the rear most is the one that goes to the glow plugs, the one in the middle is the one for the intake heater and the front one off a bit is the power in. Is this what you are after?

Glow plug controler , location top driverside of engine mounts on or near turbo. has stud posts to conect wires to not a conector plug. (2 Blue wires one is blue with white tracer)
Expert:  GM Tech (Cam) replied 4 years ago.

OK there is a plug on top, but yes the power in and the power out is for the glow plugs and the intake heater. As I mentioned, the rear most stud goes to the glow plugs with the light blue. It goes straight down to the rear most glow plug first.

The stud forward of that is the other fuse link.

THese show the glow plugs.

The rubber covered one to the left of it is the intake heater.
