Adding Park Assist Pilot

[Joe558]

I'm trying to add Park Assist on my 2020 S60. I already have 8 sensors, wanting to add the 'side' 4. All of the instructions I found online indicate to add wires to pins 37 and 42 for the front sensors, which makes sense. However it also says that sensors should be in pins 28-33 for the rear(new sensors using 28 and 33), however that does not jive with my connector. Is there a wiring / pin diagram specifically for my vehicle? All the others I've seen are for SPA models, but different make / year and none of them match my vehicle.
