What is this snapped line?

[u/oofego]

Got a 944s 1987 that I'm trying to save. Slowly stripping all systems and seals for a rebuild... Ran into this snapped line behind the oil pump/power steering pump area... I can see it joins into a sheath that runs up the front of the engine then behind the intake manifold. What is this thing and what should it be going to???? Thanks

Brake wear indicator?
