How to wire the Logic Level Shifter and factory print head

From the BOB 12009 to the SKR 3 EZ:

Run a wire from HV to Z-Stop +5V. This supplies a 5V reference to the shifter chip.
Run a wire from GND to GND. (jump the two grounds together)
Run a wire from GND to Z-Stop GND. This allows the shifter to reference mainboard ground.
Run a wire from LV to Z-Stop PC0. This pin is set to 3.3V in the SWIO Config File and allows the shifter to supply 3.3V when 5V from the strain gauge is sent out.
Run a wire from LV1 to PROBE PC13.
You will skip using the PROBE GND connection on the SKR. The shifter is providing ground reference.

From the BOB 12009 to the Swap Board:

From the Swap Board to the SKR 3 EZ:

Run a wire from PRBRST to SERVO PE5. This is the pin that resets the strain gauge.
Run a wire from 5V to SERVO +5V. This is the pin that powers the toolhead components.
Run a wire from GND to SERVO GND. This is the ground reference for the toolhead.
Run a wire from LED to RGB PE6. You will not use the other pins on RGB.
