Installation Warning

Ensure the harness is fully seated and locked before powering the system. Keep the OBD port area clear of debris to avoid connector strain or intermittent faults. Confirm your specific PowerStep part number requires this harness — not all AMP systems use the OBD pass-thru interface. Once installed, the harness is non-returnable if wiring has been connected.
