Lucas wiper wiring

Hi, Currently designing system for a triumph gt6 using pdu 24. Final sticking point is how to wire the Lucas 2 speed wiper motor and cam type park switch. Does anyone have any experience of this? My current thoughts are either single wiper output from 08 with speed control via pwm and input from the park sensor to control parking or keep things close to original with 2 pdu speed outputs and a constant live and allow the parking switch to control parking as per the original. From a simplicity perspective first option would be preferable. But can’t find much evidence of it being successful on Lucas type motor.
