Can anyone ID this plug on the back of a SCV6? (Solved)

I recently picked up a 2016 Lux at Auction, and I'm just starting to get into what it wrong, and after noticing the obvious electrical line to Injector 4 being cut, I went around the rest of the motor and found this random plug dangling on the back passenger side of the engine. It was getting dark and starting to rain so I stopped for the night, it should be nicer on Saturday so I'll be able to futz around more with my boroscope to try to see more, but in the mean time I figured I'd ask if anyone here immediately recognizes this.

It looks to me like the plug end broke off of something and the wiring harness is still attached to whatever it was. I just couldn't tell at the time what it might be.

I don't know for sure on the SCV6, but the 5.0 V8s have two plugs at the rear that are not keyed to avoid swapping. One goes to the resonator on the intake and the other for coolant temperature. It's worth checking. I swapped them after installing new engine and it drove me nuts for a week. A silly miss by the engineers.

Thanks! I've already found some funny business with other electrical lines, so I suspected this might be another. Thanks for the info.

Thanks! I appreciate the confirmation.

Appreciate the help guys.
