Andrew,
An important benefit of keeping the red wire in the connector and perhaps cutting it off a few inches from the connector is that it increases the friction forces which helps the connector stay in position in a controller such as the Cortex. When I built Cortex compatible cables I actually built a 2 row by 3 column Molex connector in the Cortex (3 pins) configuring the IO to use 2 digital adjacent outputs. I then used the two adjacent (white) signals to go to the Spike PWM cable where it became red for one and white for the other. I only used one wire for the black on both sides. Because the connector came out somewhat easily, I found myself adding a red wire jumper on the Cortex side so I now had 5 pins filled in the 2 by 3 Molex connector.

Oh yes, both sides of the Cortex to spike pwm cable were made with male pins so that no adapter was necessary to be used in the Cortex like the typical use of a pwm extension cable.

BTW, thanks for your posting Colin S on the PWM cables from Hansen Hobbies ... very helpful.
