Installation Notes and Tips

Verify connector shape, terminal count, and vehicle equipment before installation. This CBS-1338 uses a bolt-on mounting style and a single rectangular connector, so matching the original switch configuration is important on Dodge Ram, Dakota, and Durango applications. Confirm whether the vehicle is equipped with electronic stability control, since some listed fitments exclude that option.
