83 6.2 Liter, what are these?
 

I THINK A is the controller for the glow plugs? I have no clue what B and C are.

B & C are broken, I want to replace them...but I do not know what to order! lol

If A is the Glow plug controller, it is shot as well...the truck has a switch for the glow plugs. But if I could get them working, I would like that better.

Thanks guys!

Vacuum control solenoids for the EGR would be my guess.

None of those are the glow plug controller.the controller is mounted on drivers side fender inside.

No, the RELAY is mounted on the drivers side fender...the CONTROLLER is mounted elsewhere...and I think it is that one.

A-glow plug controller. B,C- egr control solenoid.

Thanks Junk!! It never hurts to have a 2nd or 3rd opinion! lol

Problem I have up here is that I cannot find a parts house that has a diesel dude working there. They almost all seem to be ricers these days.

There are a couple of gasser hot rodders...but no built diesels...let alone something so old it doesn't even have a turbo! lol

Sign of the times I guess.

Cheers!

Thanks Racer! If I run into something I can't figure, I will have to give them a call! Probably won't unless it is something like that tho, since they are 4+ hours away...but I am putting them in my phone so I have them, since I drive past there a few times a year for vacation and stuff.
