Ender 5 pro bl touch set up

Hi Nikoli, i have made some progress. Got a new main board 4.2.2 32 bit and its installed and working. So now i would like to get the BL touch to work i see the board had a specific spot for it. I have also read that using the V1 unit I had to switch two of the wire locations on the plug for the ground and the VCC correct?
lastly in reading your post on how to install the updated firmware for the new board via the SD card my last questions is which one I see two and don’t know what the difference is between them.
Ender-5 ProMarlin2.0.6HW4.2.2GDBLTouch or
Ender-5 ProMarlin2.0.6HW4.2.2BLTouch without the GD both have the same date 29 Nov 2022?
Hopefully this will get out of your hair, thanks again for taking the time with me.
