if you go to sparkfun and get an ipod connector it works great, i already had some to do this mod and didnt end up using these images as i had a sony schp 110 controller so i had to use my multimeter to try it out myself but i think i made the cable too small :P.
ill get some more kynar wire and another connector so i can re do it

.
EDIT:
got the wire i just need the connector from sparkfun now :P.
