How does this harness and solenoid replace my factory parts?

The kit is manufactured to be a direct replacement for the original vacuum harness and the boost solenoid, matching the factory connectors and routing to minimize modification. It replaces part numbers F81Z-9E498-DA (vacuum harness) and F81Z-6C673-AA (boost solenoid), making it suitable for plug-and-play swaps on compatible trucks.

• Direct-fit replacements for the specified OEM part numbers.
• Factory-style connectors and mounting points for quick installation.
• Pre-tested units to ensure electrical and vacuum integrity.

What materials and durability features are included?

The vacuum harness is wrapped in a synthetic plastic shell that resists abrasion and environmental damage, while the solenoid uses robust plastic housings to withstand underhood conditions. These materials are chosen to resist corrosion and extend service life compared with aged, brittle factory components.

• Wear- and corrosion-resistant plastic construction.
• Protective outer sleeve to shield wiring from rubbing and heat.
• Quality control testing to verify durability before shipment.

Which vehicles and engines are compatible with this kit?

This assembly is designed for use on Ford Super Duty trucks and Excursion models with the 7.3L PowerStroke diesel from model years 1999 through 2003. Verify your vehicle’s year and engine to confirm fitment before ordering.

• Fits: Ford F-250, F-350, F-450, F-550 (1999–2003) and Ford Excursion (2000–2003).
• Engine: 7.3L PowerStroke diesel only.
• Replaces: F81Z-9E498-DA and F81Z-6C673-AA OEM parts.

What should I expect during installation and aftercare?

Installation is straightforward for anyone familiar with turbo vacuum routing and underhood connectors: unplug the old components, route the new harness where the original ran, and secure the solenoid in the factory location. After installation, inspect vacuum lines and connectors periodically and follow routine maintenance to preserve performance.

• Comes as a 2-piece set: 1 vacuum harness line and 1 boost solenoid.
• Designed for simple plug-and-play replacement with factory clips.
