Description
When an AMP PowerStep installation has a failing or damaged OBD-II harness module, the manufacturer offers a targeted replacement instead of an entire step assembly. The Chevrolet/GMC-specific module is 19-04763-92.
Its two-wire lead is designed to integrate with an existing plug-and-play running board setup. Do not confuse this with a vehicle ECU, diagnostic scanner or the Ram-specific AMP module. Verify electrical matching against the original PowerStep installation manual.
