If I remember correctly, only old mainboards need an adapter. You do need to remove the Z limit switch connection from the mainboard since BL touch is the replacement of the Z limit switch. 

Good day,
I have now converted the printer to the BL-Touch and connected it as shown in Figure A. I used the version "4.2.2 Ender-3 pro 32bit Marlin2.0.1 BLtouch V1.1.2without adapter board.rar" as firmware

Unfortunately, the nozzle is rammed into the heated bed again and again for no reason.
Is this a fault of the sensor or in the firmware. Is wiring A or B correct? I can find both on the internet and some Forums.

Thank You

Hoi all

I am new on the forum

I have put the BLtouch v3.1( special version for the ender 3v2 with adapted cable and bracket and no adapter print ) on my ender 3V2
The motherboard is a 4.2.2 one with the connector for the BLtouch on itI just opened the undertray to put in the cable on the white connector and closed everything back(
So i took the firmware who was on the creality website from 29 august 2020
https://forums.creality3dofficial.com/ender-3-v2/ender3 V2-4.2.2-32bitMarlin-2.0.1_V1.3.1-BLthouch
(The original firmware was 1.0.1 out of the box)

Then i formatted a sd card in Fat 32 and putted the *.bin file of the downloaded file on itPutted it into the printer and powerd up , black screen like explained , but the printer is not coming out of it
What goes wrong ?

any sugestions ?

I toked afterwards ( to try )  the version V1.1.1 and then the printer was back alive
