Unfortunatelly, there is no retroift kit for R60 which I donot understand the reason!

I've tried to list all the parts needed to complete the installation. However, I could not find the wiring i.e. from switch cover to seat module. Is there a seperate cable or it is included in instrument panel wiring harness.

1 61356926435 Seat module X 2
2 64113456241 Switch cover, front driver side X 1
3 64113456240 Switch cover, front passenger side X 1
4 64119806858 SWITCH COVER X 1
5 52109806484 Heater element, Sport seat X 2
6 52109806485 Heating element, sports backrest X 2

I've found a wiring set with part #52109805676 - Wiring set seat, however I could not verify that this the wiring I'm looking for.

Any of you have experince on this?

Regards
