i have found that on my ca the pcm turns one of the small leads into a ground, which activates the relay. This is the way that it controls the switch

Heres a picture of a CA truck controller from doing a quick google search

It looks like the CA controller is solid state, instead of mechanical, maybe to PWM pulse the glowplugs?

Thanks,

No sir, I didn't say that. What I am saying is that the GP's stays lit even after the motor starts. The GP's seem to come on for a predetermined length of time, but if the motor is upto temp, the GPs won't come on at all.
