Here is a schematic of the controller wiring I worked up:


The PWM cable that it comes with is designed to pass through everything to a CPU heatsink for air coolers. I used it to pass through to the 35X, but that's why they use all four pins including power and RPM sense. Only the PWM wire and ground actually go all the way to the controller though. They also include on RPM pass through from the fan to read fan speeds of one channel. Using these cables I can read both my pump RPM and my fan RPM of one fan.

Can the pwm channel that you have your pump on just handle regular fans ?
