Internal hard drive power connector type?

[bilbomacuser]

Do anyone know what the connector type is called for the internal hard drive power cable that attaches to the motherboard?  The end that plugs into the SCSI hard drive I gather is 4 pin molex, but I cannot find what the square connector that fits onto the motherboard is called.

I bought a Macintosh LC II  case and motherboard, and I've checked the motherboard is working by testing it in my original LC II which still has a working hard drive and floppy drive.  I have a spare power supply, so I was thinking of fitting this LC II with a SCSI2SD card, but I cannot work out how to get an internal hard drive power cable.  Ideally I'd like to buy the connectors and make up my own cable, if they're standard components.

All the mothern ATX PSUs have 4 pin square connectors called "P4", maybe you can search on eBay or Aliexpress and see what matches with the molex connector with your LC, or maybe you can do a very dirty thing: remove the pins from an ATX connector (I think the pins from the 20 pin plug are the best for this job, they are thinner than the pins in the IDE molex plugs), solder a male Molex plug to them, put the pins part into the LC female port and hot-glue them... Yeah, it's so raw

The P4 connector is identical.

Is this the one you're looking for?



P4? at Digikey

Yes exactly.  Thank you.

Okay, if you order that from Digikey, it is just a housing.  The metal pins that go in the holes are not included.  Scroll down to the "Associated Products" section to find the pins that you need.    There's also a section for "Mating Products" which can be handy, if you've found the motherboard connector and need to know the cable connector that mates with it.
