need cables for Audio Alchemy

I need to purchase or construct power cables that connect the PS2 to a DITB and a DTI. I've got all materials but need to know which pins to solder to. I used a tester and found various combinations out of the 6 pin DINs but I'm told not to use this method. Surely someone must know- it can't be that difficult but I'm second guessing myself and would like an opinion from a fellow hobbyist.
