It gets a little tricky when using the ZIPLink cable with "flying leads" since you must map the 40-pin pinout of the cable plug against the pinout of the card items, and you will need good lighting and good color vision since the only way you can map it is correctly identifying the various color leads, some with color tracers, but I got it right the first time. Sometimes it was difficult identifying the dark purple from the black or the pink from the orange.
