Ender 3 Pro will not auto home correctly after mainboard & BLTouch upgrades I made two updates to my Ender 3 Pro: Silent Mainboard and BLTouch.  My printer head is way out of sync now. After I Auto Home, it moves along the X-axis to the left, hits the stop switch &amp; moves back to the right. It does not move at all on the Z-axis and remains 3 - 4&quot; above the bed during and after Auto Homing.
Here's the detail :
I installed a Creality Ender 3 Pro New Upgrade Motherboard Silent Mainboard V4.2.7 with TMC2225 Driver Marlin 2.0.1 &amp; bootloader pre-installed &amp; then a Creality BLTouch 3D Printer Upgraded Auto Bed Leveling Sensor Kit (the kit that comes from Creality with everything you need to install). I imagine I attempted too many upgrades without verifying the printer worked properly when I did the first upgrade which was the mainboard?
I purchased this Ender 3 Pro back in April 2020. It was working great until I decided to make the upgrades. I assume it came with an 8-bit board but not 100% sure. The new board is 32-bit and not sure what that would negatively impact besides maybe the LCD screen which does work fine after the upgrade.
Here's a video of the printer attempting to Auto Home :  

                
            
Note: Disregard the unhooked cable under the printer bed in the video.  It is totally disconnected and leftover from the BLTouch install.
Here's how I did the upgrade :
First, I simply replaced the new mainboard, and with the mainboard cover and fan back in place, I powered the printer on. The only thing I did here was to verify that the printer would power up ok.
It powered up just fine. The nozzle head did not move I don't think when powered on.
Next, I followed the instructions for the BLTouch that came with the kit.  I followed the instructions for the Creality V1 Mainboard 32-bit. Here, I upgraded the firmware via an SD card as suggested. The firmware I upgraded to is the Ender-3 Pro_4.2.7_BLTouch_Marlin2.0.1_V1.1.2_TMC2225.bin.
Finally, I powered on the printer with the BLTouch plugged in and new firmware installed. The BLTouch lights up and the touch sensor clicks out and in and few times.
Now, when I hit auto home the nozzle head moves like I described above &amp; remains in a position that I can not attempt to print from. I attempted to follow step #6 Platform adjustment 32-bit, working through the screenshots in the instructions.  This did not work.
If helpful, here are the positions of the nozzle head during the two upgrades :

Position of the print head before install: 3-4 inches above the bed and maybe a little off-center on the X-axis.

Position after install mainboard upgrade: remained the same as before.  I just remember it powering on ok and then I turned it off / unplugged power to start installing the BLTouch.


Position after install of BLTouch: remained the same. BLTouch lights up and the sensor tip moved in and out as if it was checking something or verifying it was working.
I'm a bit lost on this issue. Any help will be greatly appreciated!

I'm using 3D4LYF's wiring scheme as I'm using the same set up I believe he is using. The two wires (white &amp; black) on the red connector go in the Z-axis endstop port on the mainboard. For the three wires on the black connector I have: blue=Ground, red=V, yellow=IN that goes in the other 5 pin port on the mainboard. I rearranged the wiring from red/blue/yellow to blue/red/yellow as suggested by 3D4LYF again because I am using the BLTouch Creality Kit. Adding photos of 5-pin port and the connectors:
Resolved : connected the white &amp; black wires to the 5 pin output on the board.  This solved the homing issue.
