Hi
Is 32217750 is the correct harness for 4 sensors and 2 front fog lights? Also, do you have a picture or a schematic for the cable from the wheel arch to the CEM?

Hello,
I’m not sure about that. I bought this harness for 6 PDC sensors. I didn’t use the two side ones, but since you’re doing the installation, I would run the cable together with the two fog light connectors.
Cable reference: 31453603.
I also bought a male connector to make my own interconnection cable.
For the fog light, one pin goes to chassis ground. You will find several grounding points.
On the forum you will find the fog light connections, or you can also check this wiring diagram. I don’t remember the exact pins from memory.
My recommendation: since you’re already running cables, it’s a good idea to run a few extra wires in case you want to add auxiliary lights, a siren, or any other accessory in the future.
If you have any questions, feel free to send me a private message, but remember that everything is already explained on the forum.
Important: from around 2022 onwards, I believe the PDC control is no longer handled directly by the CEM, so this manual may not apply.
