Hi, first of all how was the SLS disabled? if it was properly done with a diagnostic tool then that audible warning is not from the suspension cos it's supposed to be silent. If the light was just simply "killed" with some rudimentary method the SLS warning must be disabled properly aka the vehicle set for coil suspension otherwise there will be excessive quiescent current drain even if the warning was botched. The "buzzer" is actually the IP's speaker which works for all the systems so if you disconnect it you'll lose all the audible warnings which is silly IMO. If you'll forget the lights on in a sunny day without knowing it then when you get back to the vehicle you'll find it with flat battery.... and so on, that speaker is quite important.
