Standalone for 2006 2.0T - how is LP fuel pump controlled?

Getting ready to attempt 2006 2.0T GDI Passat first start on a custom standalone. Does anyone know anything about low pressure fuel pump control - is that on/off? PWM? CAN? something else? I know this engine has low fuel pressure sensor but do not know if low fuel pressure is constant or if there is some control strategy? My preference would be not to poke scope probes into wires.

The pump is pwm but I don't know the parameters for the pump or the module input.
It works nice for sure, I have some billet cover plates for them now too.
