How can I mod something to drive these pumps?

Only way to chase a signal such as PWM is with an oscilloscope. Costly piece of gear, although these days there are dongle options available that work with a PC. Aside from the controller, it's good to know more about the pump motor as well. Is it a brushless PMG DC motor, any additional circuitry in the motor or pump housing?
