The wires are all connected. I am using ac power. No blue lights on my boards, however. But, I can SSH into my box without a problem.
Here's the errors:
pi@WeatherPi:~/SDL_Pi_GroveWeatherPi/SDL_Pi_TCA9545 $ sudo python testSDL_Pi_TCA 9545.py

No blue lights on the board? you have no power to the boards.
Something is wrong with your wiring. Send a picture.
Run i2cdetect -y 1 and post the results.

Fixed...
I only attached one-half of the GPIO headers. Duh.
