I'm in the process of replacing the Plenum on my 1998 K1500. I have all the connectors labeled that I disconnected, but I cant seem to find one for this port.
What connects to this opening with the red arrow?

I'm a dork. Its for the Vapor Canister Purge Valve, which I left hanging out of the engine bay and didn't see it while looking at connectors.
Some ports or holes can be those used during machining to get all the others in the correct locations.
Or it could be where locating studs fit.
Or, if you check with the gasket, that one could actually be blanked.
Best way is to take pictures before taking things apart if it is the first time.
