I was able to determine that the IR sensor is wired as follows:
Terminal A - wire 11 should be the output
Terminal B- wire 1 (red) should be ground
Terminal C - wire 10 should be 3-5v
However, i found a couple different terminal configurations.
I do not know what frequency IR sensor to use. There seems to be 2 common freqs, 38.5Khz and 56.8Khz.
