Can't find the wastegate

I just bought this truck a few weeks ago and need help I'm completely baffled I can't find a wastegate anywhere but the truck keeps throwing a wastegate malfunction code. It won't build boost and black smoke so thick you can't see the cars behind you

Not that i'm aware of. That looks like an older version of an A T turbo but there should be a wastegate somewhere..

Better pics will help

I don't see an oil return line or a wastegate anywhere.

I would get rid of that thing and get another turbo..

That's what has me baffled and they have the boost gage tied directly into the top of the intake and I just replaced the wastegate soliniod only to find no vacoom lines running to it or from it

Ok, I just noticed something in your first pic..
Take another pic of the Turbo...
I need a shot of the intake to the Turbo ( inlet side).
Stand at the grill and take a shot looking at the turbo

The area I circled looks like an oil port

I sure don't see any wastgate controller there at all, manual or otherwise.

Your blue silicone intake hose looks abnormally swollen. Is it busted or leaking?
