Hello Rickard,
Okay so the paper tells you to what pins the PFET outputs are connected; It is connected as follows -> p259 output as on paper is connected to pfet gate (control signal) -> pfets are fed from ec36-pin25, pfet output is connected to the corresponding p259 output pin (the normal internal connection from p259 to the ec36 output is disconnected).
I hope this clears things up for you; If you have any further questions, feel free to ask.
Best regards, Dave
