Aaron,
The white wire is the signal wire, so what you did was tie the digital input of the RC and the signal output of the sensor to +12 volts through the sensor. What might have occured at this point is anyone's guess. As to the ground wire heating up, it is taking all the current that is passing through both of the other wires so it will heat up faster. The RC inputs are fairly well protected but this may have killed them and the sensor as well.
I went back and checked the sensor paper again after Chris posted and it is very misleading...
"c. Generally, the “B”, “R”, and “W” connections connect to ground, +5V and signal respectively."
