HELP! Needing assistance installing smart light switch on an old circuit

Hello everyone, this is my first post here, so please excuse my naivety... I have a Quirky+GE Tapt Smart Switch I'd like to install in my bedroom, however I have quite an old light switch installed and really don't have much of a clue as to how to identify what is what... Here are a few photos of the wiring as well as the wires on the back of the smart switch. If the photos don't work, my best description would be that there are 2 black wires connected to the existing switch, 2 more white wires that are paired together, and finally 2 bare ground wires. The Tapt switch has a red, black, white and green wire.

Any help as to identify which wire is what would be very much appreciated!

You can not use TinyPic to post pictures. http://www.doityourself.com/forum/li...rt-images.html
The Tapt switch has a red, black, white and green wire.
  • TapSwitch black to power in house black.
  • TapSwitch red to power out house black.
  • TapSwitch White to house white group.
  • Green to bare.

You will need to use a multimeter or neon test light to determine which house black is power in. (A non contact tester won't work.) Measure from bare ground to each black. (Blacks must be disconnected from the switch.) The one that reads `120 volts is power in.
