Retrofit Keyless Entry

[Pliind]

1. Hello. I started installing keyless on my car (2019 V60). At the moment, I have replaced the wiring harness in the doors, the handles and the rear antennas. I activated the keyless function and noticed that the rear handle lighting does not work. I replaced the front handles with the back and the LEDs are good. I checked and indeed they go to pin 8 and 23 in the door module. Does it have to do with the fact that I haven't pulled the wires for antennas and signal in CEM yet?
   

Sorry for not answering the question but do you have part numbers for the harnesses you've bought? 

I'm right now researching the differences between all versions im finding in swedish scrapyards.
