Product Description

The AMP Research 19-03473-93L is the factory-matched replacement wiring harness for AMP Research PowerStep electric running boards installed on the 2002-2003 Ford Excursion and the 2002-2003 / 2008-2016 Ford F-250, F-350, F-450, and F-550 Super Duty. When a wiring harness fails due to corrosion, physical damage from road debris, or age-related degradation, the PowerStep steps lose their ability to receive the door-trigger signal required for automatic deployment and retraction. This replacement harness restores that electrical connection, re-enabling the full automatic operation the steps were originally designed to deliver - extending when any door opens and retracting approximately 2 seconds after all doors are closed.

This harness is specifically engineered for the Ford Super Duty and Excursion electrical architecture of the covered years and is not a generic or universal wiring solution. The connector configurations are vehicle-platform specific, ensuring integration with the factory door sensor circuit without cutting or splicing additional wiring beyond what the original installation required. Note the year gap in coverage: the 2004-2007 Ford Super Duty generation is not supported by this harness - owners of those model years should contact AMP Research directly to identify the correct replacement harness for their specific platform and PowerStep series.

Before ordering, it is critical to confirm the specific series of AMP PowerStep installed on the vehicle, as AMP Research produces multiple harness variants that are not interchangeable across PowerStep generations or vehicle platforms. If the exact PowerStep part number is unknown, AMP Research's technical support line can assist in identifying the correct replacement. This product is classified as a final-sale item - all purchases are non-returnable and non-refundable unless the harness arrives with a confirmed manufacturing defect.
