Installation Notes and Tips

Verify connector shape, terminal count, and harness length before installation. Confirm front-position application and compare the original sensor to AB0525 to ensure the same electrical interface and routing. On Mercedes-Benz R320, R350, R500, and R63 AMG applications, inspect the tone ring and surrounding wiring during service to avoid repeat faults.
