In an attempt to trim the size of the connector, a 25-pin SCSI connector was designed for narrow SCSI.

First of all, remember that SCSI II is obsolete and is not used today or rarely.SCSCI II stands for Small Computer System Interface (Revision 2)SCSI II operates with a 32-bit data bus with an A cable and a B cableThe A cable consisted of a 50 pin Centronics connector. Pin outs here: http://www.interfacebus.com/SCSI_Differential_A_Cable_Pinout.htmlThe optional B cable consisted of a 68 pin connector**Click on the related link below
SCSI Harddrive:80-pin Connector The SCA interface was designed to provide a standard connection for systems using hot swappable drives. SCA interface drives connect to a SCSI backplane that provides power, configuration settings such as SCSI ID, and termination of the SCSI bus.
The beauty of SCSI is that supports many physical interfaces. Fibre channel SCSI uses 4 "pins" which can be copper, or fibre optic cabling. Parallel scsi which you are probably asking about can use 25, 50 or 68 pins. So you should rephrase your question to specify the interface you are asking about ... but I guess that would liook kinda dumb, ... "How many pins does a 50-pin SCSI interface have" :)
68
Mostly 68. There is centronics 50 pin, HD 50 pin or HD 68 pin. Also some micro D-type connectors, and cheap-junk SCSI uses 25 pin but don't buy it. Also, SATA and various other modern interfaces are basically SCSI logical protocol over a serial layer 0.
The 2 pin conecter is for computer communication
it is a 34 pin connector
A DIN connector has a 5-Pin connector
24 pin connector is required to supply power to the motherboard.
I got a 7 pin connector with harness and used the color code and put it to 6 pin green to left etc
