I pulled the old outlet and there are two black wires inserted into the back of the outlet and two white wires inserted into the other side of the outlet (plus the ground). the insteon outlet has one black, one white, and a ground. I already tested all wires and one of the black wires is hot but none of the others. Do I twist the 3 black wires together and the 3 white wires together?

So far, none of the wiring diagrams that comes with the instructions has matched anything in my house lol.

Yes, as you said.

Only one of your blacks is live because the other is relying on the connection to bring it power (parallel circuit).

 

I'm not trying to be rude here at all, but I would recommend picking up a DIY electrical book to review common circuit wiring.

The circuit you described is very common and you should have a good understanding of its principle before changing house wiring.

Thanks for the quick reply and point taken.
