Question
Is it possible to connect a toro wireless sensor 53770 to a toro greenkeeper 212? If so how do I get the plastic front cover off to see where I connect the wires?

Answer
Hey Mar, simply slide the lower housing cover down towards the bottom of the controller. If you look inside on the left side under the fuse, you will see the connection marked sensor, this is where the sensor will hook up. Good luck and have a great day.
