Could someone help me with the jumper settings of my floppy disk drives?

I want to make the 3.5 inch drive Drive A and 5.25 inch drive Drive B.
Drive B will be an external drive and somtimes not hooked up to the PC.
I have made my own straight through cable (it has no twist in it).

First drive: Chinon  
             Model FB-357  Rev. B  
             (1.44 M , 3.5 inch)
Top
____________________________________     Default setting: PJ3 (2 and 3 shorted)
        o o-o PJ13      [o o o o]  !                      DS0  closed
        1 2 3            power
                         connector       What is PJ3 for or do ?

                                         How do I terminate or not terminate
                                         this drive ?

Bottom                                   does not require termination.

Second drive: Chinon
              Model FZ-506  Rev. A
              (1.2 M , 5.25 inch)
Top                                    /  Default setting: 3,10,13 closed

          13   10         3     1         This will be the last drive on the
                                          chain ie.needs to be terminated.
