I assume that this rule is about the signals, and not the actual cables, but I wanted to check to make sure everyone else was reading it the same way I was. "PWM cable" does not need to be the exact cable purchased from IFI, so long as it is the correct AWG (by R90), and has the correct crimp connectors on the ends, correct?

By the way, if you are looking into making PWM cables yourself, I found that newark.com had much lower prices than digikey on the pins and housings, although they did not sell the molex crimper.

Toby,
The PWM cables are available in any length, from almost any hobby shop in the country. Many teams make their own by buying 3 conductor ribbon cable and the appropriate housings. Newark does sell these items and the crimper but (and this is a big one) the Newark minimum order is beyond most teams. I believe at last count is was $125 not including shipping. Even I have stopped buying from Newark (at work) for most parts due to the high minimum.
