Afinibot A9 BL-Touch Wiring

Good day,

I would like to find out if you have a wiring diagram or pinout of the Afinibot A9’s controller? The reason for asking is, I want to connect a BL-touch probe but cannot find pin 27 (Buzzer pin) to the LCD as the BL-touch also uses that pin. If you could point out who I can ask or where, I would greatly appreciate it.

Hey @24sevenguy

Unfortunately, the only documentation for this printer is the following:
