dd501 cables

[ownthesky2010]

Hi all.
Total noob here. I just bought a dd501 electronic kit on ebay that is missing its cables. I have managed to sort out most of the connections but Im still battling with the hi-hat and pedal. The cables are grouped together to a db25 plug in the brain so its not just a simple case of plugging things in and seeing what happens. Does anybody have a pin-out diagram for the plugs. If not, can someone with a dd501 and a multimeter please just check which connections for the hi-hat and pedal go to which pins on the main connector so I can duplicate this.
I would really appreciate it as Im keen to start learning drums.
