How to utilize BLTouch Connector in Creality 4.2.2 Board

Hi, Does anyone know how to configure Marlin to use the BLTouch connector on the Creality 4.2.2 motherboard instead of the Z Endstop connector?

I have just brought Ender 3 MAX. On such a big plate I have to use ABL. However, Creality’s own firmware does no work or I don’t know how to get it working.
I have compiled the Marlin 2.0.7 to work with Z Endstop connector.

The BLTouch fails randomly during the bed leveling process. The BLTouch is OK. I have tested it in Ender 3 V2.

As the last hope is to get the BLTouch connector to work, but I cannot find any info about the configuration. Any ideas?


I finally found the correct value and got the BLTouch working through the connector.
