There is no app or settings menu for it, if you have installed it then you are good to go, if you do want to turn it on and ff once you have finished fixing your Cydia error then you can just use SBSettings, alternatively you can just uninstall it when you are down with the guide if you don't plan on SSHing into your phone again
