Hey! thanks for letting me join, I just purchased two ender 3 pro’s I have upgraded the board to 4.2.7 V2 on each of them.. Also added the CL Touch and the Filament sensor… 
Put everything back together and now, when I try to either Auto Home or create a new mesh for bed leveling, the Z axis is in reverse… Instead of going down to the build plate.. it is rising until I stop it…. Please see attached video…. 

I checked the wiring, I am pretty sure everything is right…
