EZ-0 enable pin

I am running two DC motors from a Solarboics driver board that has two enable sockets. Brandon Sweeney's sketch (Instructables) includes each of these as well as a pin to shut the EZ down. Problem is, I don't know where this jumper should end. On the driver board or one of the sensor through holes? I have looked at the data sheet and can't determine if this is the author's intention. If you have experience with EZ , please advise a solution. Thanks.
