I purchased a 37-conductor cable from Jameco Electronics last year which I will be using to connect some Grass amplifiers. I cut the heads, and inside there are a bunch of colored wires. I need to hook up 33/37, which means I might as well do them all.
| Red | Red/Black | Red/White |
| Yellow | Yellow/Black | Yellow/White |
| Orange | Orange/Black | Orange/White |
| Dark Green | Dark Green/Black | Dark Green/White |
| Light Green | Light Green/Black | Light Green/White |
| Dark Blue | Dark Blue/Black | Dark Blue/White |
| Light Blue | Light Blue/Black | Light Blue/White |
| Purple | Purple/Black | Purple/White |
| Brown | Brown/Black | Brown/White |
| Pink | Pink/Black | Pink/White |
| Gray | Gray/Black | Gray/White |
| White | White/Black | |
| Black | Black/White |
Now the tricky thing is that I'd like to split it into two chunks of 16 so that it is easy to flip connection... ok, I got it. I will have a "dark" side, and a "light" side.
| Plug A | Plug B | |
| 1 | Red/Black | Red/White |
| 2 | Yellow/Black | Yellow/White |
| 3 | Orange/Black | Orange/White |
| 4 | Dark Green/Black | Dark Green/White |
| 5 | Light Green/Black | Light Green/White |
| 6 | Dark Blue/Black | Dark Blue/White |
| 7 | Light Blue/Black | Light Blue/White |
| 8 | Purple/Black | Purple/White |
| 9 | Brown/Black | Brown/White |
| 10 | Pink/Black | Pink/White |
| 11 | Gray/Black | Gray/White |
| 12 | White/Black | White |
| 13 | Black | Black/White |
| 14 | Red | Pink |
| 15 | Brown | Yellow |
| 16 | Dark Blue | Light Blue |
| Gnd | Purple |
That should take care of it.
Update
I decided to hook up the last few wires too... so after the 32, I'm going Gray, Dark Green, Light Green, Orange, Purple(Gnd).
