Update 1 Feb: Printer up and running again. Took the opportunity to add an extender to the screen SD card slot so I do not have to disassemble it for access. At the same time I installed and configured klipper too, including the touchscreen mod.

I'll post this here for anyone else with the Pro V2, here is a link to the Z-cables I used, as a bonus they were under $10. They worked without modification (I had read that some of the pins may be flipped for the Ender.)
