I got few pictures of what directly above the 'mystery' unit.
I think I'm wrong about it not connecting to anything. It apparently does.
I'm not sure about the function of this unit, but I can see it's connected to vacuum lines.
BTW guys, don't think I'm crazy to have those wires running around the engine bay.
They are not connected to anything. I keep them in case I need them in the future for diagnosing or fixing wiring problems.
It's a left over from a diagnostic job on the air conditioning unit last year. I left the wires just in case I need them for
something else in the future.
So, I'm wondering, what does this canister unit do?
It's obviously connected to vacuum lines.
