[GreenKeys] 28KSR question...

[John, W9DDD]

OK, the more one digs into this stuff the more you find that there are a 
lot of deviations from what appeared to be a standard.

Just some quick looking at WDs, I see that if there is a second 
connector on the typing unit, they generally put the bell contacts on 
pins 3 and 4 of the right connector.  If you don't have a cable to 
connect to the right connector of the typing unit then you can safely 
bet that typing unit didn't go with that cabinet originally.

So you'll probably have to move the wires on to the generally used pins 
on the left connector.  On typing units with only one connector the bell 
contacts were wired with a red and a black wire and the bell contacts 
were over slot 28.  With one like yours the bell was wired with yellow 
and brown and went to pins 1 and 3 on the right connector.  (Y on 1 and 
BR on 3)
