Installation Notes and Tips

Verify connector shape, terminal style, and vehicle application before installation. This sensor uses a female oval plug-in connector with 3 male blade terminals, so matching the harness connection is important for proper fitment. Confirm the vehicle’s brake sensor location and compare the original part number when servicing a Chevrolet Cruze, Buick LaCrosse, or Cadillac SRX.
