Same as the other 5.25" drives. That's why they are called "SA400
interface". Such as drive selects on pins 10, 12, 14, . . .
But some newer drives have added SIDE SELECT (for double sided drives),
and "density" for multi-media drives, such as 1.2M.
Termination is required on the last drive on the cable. Lack of proper
termination can make for flaky operation, but will not generally
prevent it from working.
Power connection isthe same as all other (well, ALMOST all) 5.25" drives.
The SA400 is a 48TPI, 35 track drive. Most drives that replaced it added
another 5 tracks.

I've never seen a factory switch on the front of one. Are you sure that
that wasn't a user added switch, such as one to override the write-protect
for flippies?
