[Elecraft] aux Y cable that really have 15 wires

[elecraft at g4fre.com]

Can anyone recommend a source of "Y" cables, currently available, for the 
AUX cables that actually have all 15 leads paralleled up?  Recently i bought 
(and returned) 2cables from 2 well known electronic stores which were 
labelled "15 through connections" but were not! 

Currently I have homemade versions but i need something neater for my wifes
