Creality Ender 3 Pro 4.2.7 Silent Mainboard BLtouch upgrade repair troubleshooting Marlin 2.0

I got this from a customer that attempted to install a BLtouch. He originally had a 4.2.2 board. Its was worth $35 to upgrade to the newer silent board with trinamic drivers. This unity also had the creality 5 pin connector BLtouch. I'm actually surprised how well this prints with creality's stock firmware.
