2 possible ribbon cable solutions, one with connector at each end,
other connector only at HV card end
All SC umbilicals from HV card side identical.

Direct coax possibility with braid EMC screening, soldered at HV card end,
connector or soldered at Mothercard.
Maybe best noise performance with this system.

Possible mapping solution, done inside connector, top and bottom sides of MB
MB with umbilical + free pins, all identical until position on Dee known
Then pins to connector in specific order for that position.
All SC umbilicals to mating connector identical.

3 MBs together for the 'short' cooling bars on EE
