Re: Turbo Lines
well Letter C isnt missing anything. You can see parts of the original foam filter thingy that was originally on there.
You will also see the vac. line thats next to the orange elbow in your pictures, that line hooks to I believe Letter A, but im not 100% sure on that.
As for Letter B, hooks into the actuator (the gold thingy with the arm on it) that should be on the bottom side of the turbo.
Also the other problem I noticed is you have no wires going to it. You see the part that has the DeloRemy name on it, well thats a plug for the wiring harness, so hopefully that wasnt cut off.
Just out of curiousity, is there an aftermarket boost controller installed somewhere on the truck? that would explain why that is disabled and not in use anymore.
