Installation Notes and Tips
Verify connector shape, terminal count, and attachment style before installation. The AX324 uses a rectangular plug-in connector with a push-on attachment method and no wiring harness included, so the existing vehicle harness must match the sensor connection. Confirm fitment by year and model before ordering, especially for Audi A4, A5, Q5, and S5 applications.
