Help! What hose connects to this sensor?

[MC Hammered]

I was doing a visual inspection after checking the dipstick and saw this was disconnected. Anyone tell me what hose it supposed to connect here?

[kronus]

vac line to SAP valve

if your engine is OBD1 converted or has SAP deleted in the ECU, you don't need it

Thanks Kronus.

I assume I should just cap it off or is it no big deal to have it open?

[kronus]

If it has a vac line coming out of the bottom, probably better to cap it. With a SAP delete the solenoid should never open, though, so this is just paranoia speaking.

I'll check again but I didn't see an open line below the manifold.

If the SAP is deleted, then I should be able to disconnect the solenoid right? Or is it best to leave it there to keep the harness connector free of debris? This is paranoia speaking too! LOL!

edit: I did some digging, learned a bit more and will just cap the solenoid off.
