Hi Jean; wire color information for 4-way installation is not something we have available. To find the right wires on your 2023 Audi Q5 and install your # C56236 you will have to use a tester like # PTW2993 to identify the wires and follow the testing procedure outlined in the instructions.

@Jean-pierre good I'm glad that matched up. Wiring colors can be a tricky thing and even change within the same year for a vehicle so you can't always count on them. If you need anything else let me know!
