verify that circuits +5 volts goes to pin 41
verify that motor +5 volts goes to pin 42
verify that ground goes to pin 43
verify that disk type indicator goes to pin 44
jumpers: need to make adapter have place to put jumpers, or leave them available. if you decide to leave them available, use 44 conductor receptacles and 44 conductor ribbons. if you decide to include them in the scope of the connector, use 50 position receptacles and 50 conductor ribbon.
you may want to include a drive ready light (e.g. a green LED or the like).

I'm told that pins 1-40 are identical for regular IDE Desktop style drives, which makes sense (Different pin spacing, of course.)
