Got it!
There's a component of my WVO system that was really getting in the way. It covers right over the IP, so that made things difficult. (You couldn't see it in the pic b/c I was holding it out of the way).
Again, thank you!

I'm still wondering about that 3way thing though...

it seems to be hooked up in a different combination. Is this how mine should be?
