Need help figuring out what is missing from front of intake manifold

Working on assembling a project that I didn't tear down. Can anyone tell me what should be fitted in the hole just below the fuel line mounts on the front of the intake? Photo attached.

TPI Intake - Maybe 9th Injector

Working on assembling a project that I didn't tear down. Can anyone tell me what should be fitted in the hole just below the fuel line mounts on the front of the intake? Photo attached.

By the looks of that injector pigtail, i would say the 9th injector.

There is a temperature sensor in the intake as well, but with the injector pigtail not connected, it is probably that.
The 9th injector is for cold start ups.

So it ended up being the cold start sensor. Not sure where that went, but I found at Corvette America. They were back ordered so did more searches and found one at an O'Rielly Auto Parts store about an hour from the house so... made a trip in a snowstorm to pick up that one. FYI, it was $95 dollars.
