like i said, i hook a 12 volt LED to the output of the glow plug relay and mount it in the dash. this way i know for a fact when the plugs get power and when they do not.
I like the led idea then you know the relay is working and controller. So the led would only be on 10 seconds or the same time as glow plugs are on and it must flash when the afterglow works right lol I will use this. And after I check the relay I'll do same process to the harness because that is the only next thing. I'll post my reading and info soon

yup, the led is only lit when power is going to the glow plugs.
