As far as I can tell are our private clones of the following construction:

Apollo 1 to 3 serial connector


Sio 1               Sio 2               Sio 3

 1  -  1             1  -  1             1  -  1
 7  -  7             7  -  7             7  -  7
 2  -  2             2  - 12             2  - 21
 3  -  3             3  - 13             3  -  9
 4  -  4             4  - 14             4  - 23
 5  -  5             5  - 15             5  - 10
 8  -  8             8  - 16             8  - 25
20  - 20            20  - 18            20  - 19

Where every first column is the connection to the divided stream
The second column indicates the connection made in the joined connector
which goes in the apollo's back.
