My method for labeling cable is such:

I wrap the ends of all cables going to module A in red electrician's 
tape. All the cables going to module B are wrapped in yellow tape. 

I then place 1/2" stick-on letters on the tape. On one end, I label 
the trigger number. On the other, I label the pad type by initial 
i.e. S=snare, T1=Tom 1, HH=Hi-hat, etc. T

his seems to work quite well for fast set ups.
