We've configured the pin as an input after the device boots. Even with with 
just a jumper wire between the two pins, an output and an input, the 
behavior on the black and white is different. Here's how we set it up:
sudo sh -c 'echo "60" > /sys/class/gpio/export'
sudo sh -c 'echo "117" > /sys/class/gpio/export'
sudo sh -c 'echo "in" > /sys/class/gpio/gpio60/direction'
sudo sh -c 'echo "in" > /sys/class/gpio/gpio117/direction'
sudo sh -c 'echo "falling" > /sys/class/gpio/gpio60/edge'
sudo sh -c 'echo "falling" > /sys/class/gpio/gpio117/edge'
