Can anyone tell me what this plug connects to? I did a head gasket job and cannot find this connector.

If you have a scan tool you could start the engine and see what fault code you get. That should lead you to the component that it plugs into.

Man… :dry: I feel your pain… The head gasket job on the GM 3.4 is no joke. Hopefully it was the front head only. That looks the connector that comes from the cam shaft sensor. It may be the connector that cap269 circled. It should, however, come out of the main wiring harness that is routed at the front side of the engine. If you can get your hands on a wiring diagram, it should give you the color of the wiring on the male end (missing end) of the harness as well.
