How do I connect a controller to another Xbox in the same house?

There is a simple mechanism Microsoft has built into Xbox 360 controllers to allow them to be used on any console. There is a small button on the top of the Xbox 360 controller that is adjacent to the charging port. There is another button on your console that is similar to it right on the front. These are reffered to as the 'Sync' buttons. These do exactly what you are trying to, syncing a console with a particular controller. First, momentarily hold the button that is on the console until the ring of light begins flashing/spinning, then do the same to the button on your controller, and the lights on it will flash as well. After both the console's, and the controller's lights have flashed for a moment, the Xbox will detect the controller, and they will connect.

That's all there is to it. Here is the eHow guide in case you didn't understand my explanation - http://www.ehow.com/how_5726306_sync-xbox-360-cont...

Hope I helped! :-)

Just push the reset on the xbox and controller, they will find each other.
