[Elecraft] K3 to Yaesu Quadra Band Data 2 question

[RLVZ at aol.com]

Hi Guys,
 
Wondering if anyone has successfully used a K3 to control a  Yaesu Quadra 
by using the Quadra's Band Data 2 jack?  My K3's has  been controlling a 
Quadra via the Quadra's Band Data 1 and it works  well.  But I'd like to have my 
2nd K3 control the  Quadra via the Quadra's Band Data 2 connector.  I'm 
wondering if this is  possible, and if so, if anyone manufactures the needed 
cable to go between the K3's accessory connector and the  Quadra's Band Data 2 
jack?  (I've got eye problems and cannot wire  small cables)
 
Thanks & 73,
