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.

PWM is a reference to the pulse-width modulated signal, and does not refer to any particular brand of cable. So long as your wire gauge is at least as big as the IFI cables, you should be fine.
