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?
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.
Hi, can anyone say how many connected pins is needed for foglight and 4 pdc? My connector has a lot of cables but just plastic dummies instead of pdc in the the front. I think there are 8 cables going to the CEM from the connector.
Each sensor has 3 wires: positive, negative, and signal.
The positive and negative are shared, so there are only 2 wires for all of them.
For the fog lights, you have 1 GND wire that goes to the chassis and 1 signal wire for each light.
In total, with 4 sensors and 2 fog lights, you have 10 wires.
I’m not sure which connector you’re looking at, but the shape doesn’t look familiar to me. The number of pins and wire colors also don’t match the diagram or your connector.

This is the connector that's In front of the left front wheel behind the fender lining (wheel arch). I'll try to attach more photos. Is this not the correct connector?
Best regards
