manual glow plug
so ,i disconnected the wight wire off the controler, ran a new wire from that smaller post to a momentary switch in the cab, then a ground wire from the other side of the switch to a good ground -------nothing
no power to the plugs and all those zd9's are good.
and when i put atest light to the small post. the light comes on says it has constant power --wtf 1990 7.3

I had to run hot to the momentary switch and then to the GP solenoid. My solenoid was 12v activated not ground activated, but my truck is an 85.
Other than that, I would check for continuity between where the GP harness connects from the solenoid to the GP connectors themselves.

Try testing it right there at the battery/solenoid. Take a ground wire and touch it to the solenoid enable post and make sure you hear a click. If so, then just make sure you wire your switch between ground and that post.
I'm not familiar with your year, because, like Luke, mine is activated off 12 V.
