Garage Door Wiring
 

I am replacing a Genie OCG Series Python Model #WKYRPI309848 garage door opener with a Chamberlain PD752DS. I want to use the existing wiring from the Genie for the safety reversing sensors. Any suggestions on matching up the wiring?

The Genie motor has three screws to attach wires coming from the wall mounted opener and the sensors.
Wall Mounted Opener: Red Wire
Com: white + white + candy stripe
Safety Bar: Red wire + candy stripe

The Chamberlain motor I am replacing the Genie motor with has four quick connections colored Red + White + White and Grey

Thanks
