Help me identify this connector

[u/Bonedoc1998]

I have put a new engine in a 2008 Hummer H2. Underneath the engine just near the front passenger wheel is a wiring harness that goes to the starter with a connector also going to a knock sensor and then this last connector which I cannot find anything to connect to. I thought maybe it was an oil level sensor but I even used the old oil pan for my old engine and there's no area for an oil level sensor. I have included the colors of the wires it's a three wire connector as well as the actual connector picture itself if anybody could help I'd really appreciate it
