ds2 wiring diagram

[AlarmedBread]

sorry if this has been posted before, but i used the search function for a half hour and couldn't find anything like this...also tried google...

does anyone have a wiring diagram for the ds2 controller?

my purpose is to make an addon shifter module for my dfp, using the wiring for a controller, but rather than destroy a perfectly good controller, i'm going to use an extension cable to get the job done

thanks in advance for any help, if it turns out well i'll post a bunch of pictures on here
