The short version: There is not one cable there
You have to do all the wiring in the car, from the A and B pillars on both sides of the vehicle to the CEM. 3 cables per B-pillar, 1 cable per A-pillar and 2 cables for the antenna in the trunk. Everywhere (except in the trunk) you have to fight your way through to the door with the cable (I'm currently stuck there) - in the door you also have to build the wiring harness yourself. 3 cables for the lighting and ground of the door handle to the door control unit and the aforementioned 1 cable that goes to the CEM. In the rear doors there are 2 more cables for the keyless go antennas. You have to build everything yourself, there is not 1cm of cable. Or replace the complete wiring harness and buy it from Volvo, that's the craziness I'm talking about. The cables that have to run to the CEM get tangled up in the central wiring harness in the interior, so you have to replace the entire vehicle wiring harness.
You can't get wiring diagrams anywhere except in VIDA, which unfortunately is not currently available to me in Germany. Haynes Pro and Workshopdata both have no information about the new Volvo SPA vehicles ...
My honest estimate of the difficulty: 10/10
- remove complete interior
- most likely the removal of the dashboard
- Build wiring harnesses yourself
- Obtain all plugs and pins
- no wiring diagrams
