I am using parallel cables as quick disconnects for the controls on my driving cab. I wanted to determine which colored wires mapped to which pin so I used a continuity tester to map out the color-to-pin mapping.
After cutting the parallel cable wires I had lying around, I noticed I had three different types of cables (18 wire pair, 17 wire pair and 25 individual wires). I included the color mappings for these wire types below in case anyone else could benefit from my patience

Note1: I was told that the coloring mapping for parallel cables are not standard, so it depends on the type of cable you are working with for your project, but maybe this can help you out...
Note2: "unused" means the wire is not connected to any pin
Note3: In the (TYPE 1) cable, I believe 18 through 25 are ground so multiple wires mapped to these pins.
TYPE 1) Parallel Cable with 36 wires (18 pairs)
