How to activate old HP ProLiant ML350 G3 server power supply backplane to use with new motherboard

[luhujp]

I have an old HP ProLiant ML350 G3 server that uses two power supplies and 292235-001 backplane connector. I want to keep the case as a souvenir and use it with a new motherboard.
I have a problem, this power supply backplane works with a 16-pin jack that connects to motherboard for control, I want to modify it to use it to match the new motherboard (24 pin ATX and 8 pin CPU).

Does anyone have a schematic diagram of this 16-pin jack?
Please help me with some information about this power supply backplane

Thank you very much everyone!

HP split into two companies in 2014.

HP supports PC's, printers, tablets and calculators.

HP Enterprise (HPE) supports servers, switches, routers and enterprise storage devices.

not to mention that the best time to do this is when the system is working and you could have pined out the voltages while the system was power on just before removing everything from the case

most of the older HP ML350 series backplanes had onboard circuitry related to the drives error leds, SCSI ID'S that talked to the motherboards onboard SCSI/SAS controller  if your backplane has this you may be better off trying to install a generic "dumb" backplane that only has SAS/SATA and power jacks nothing else

Thanks

I care about is the power supply backplane of that server, other issues are not so important
