• Electrical connection issues at the reverse light switch interface

Installation Notes and Tips

Install the LS418 in the original screw-in location and verify the connector style and terminal layout before installation. Because mounting hardware, gaskets, and mounting brackets are not included, reuse serviceable original components as needed and confirm the sealing surface is clean before threading the switch into place. After installation, test reverse lamp operation with the ignition and transmission in the proper service position.
