Auxazalux Tuner Harness Plug Kit for Ford 6.7L Powerstroke — Direct-Fit ABS Snap-Fit

Auxazalux Tuner Harness Plug Kit is a direct-fit replacement connector set engineered to restore or upgrade the electrical connection for Ford 6.7L Powerstroke tuner plugs without soldering.

Designed for technicians and pickup owners who need a reliable connector solution, this kit replaces worn or damaged tuner harness plugs on compatible Ford diesel trucks. The plugs are molded from durable ABS to resist wear and maintain a snug fit around the original pins. Installation is straightforward: remove the old housing while leaving the factory terminals in place and snap the new plugs onto the pins — no crimping, soldering, or complex rewiring required. Built to preserve signal integrity, these plugs help maintain stable communication between the vehicle's wiring and aftermarket tuning devices.

Which Ford models and years will these plugs fit?

The Auxazalux plugs are made to match the OEM connector shape and pin layout used across a range of Ford F-Series diesel models. They cover late-model Super Duty and select F-150 applications where the 6.7L or 3.0L wiring harness uses the same connector family. Always verify connector appearance against your vehicle before purchasing to ensure compatibility.

• 2018–2020 Ford F-150 3.0L engine compatibility
• 2017–2020 Ford F-250, F-350, F-450, F-550 Super Duty 6.7L
• 2020 Ford F-600 Super Duty fitment
• 2017–2019 Ford F-650 and F-750 included

How difficult is installation and what tools are required?

Installation is intended to be accessible for professional installers and experienced DIYers alike. The replacement housings are push-fit: you preserve the factory metal terminals and slide the new ABS plug over them. This approach avoids cutting or soldering, reducing installation time and risk of wiring damage.

• No soldering or special crimp tools needed
• Basic hand tools to remove the old housing and access the pins
• Quick snap-fit into place for most installations
• Clear pin retention design reduces accidental loosening

Will these plugs affect tuner signal quality or reliability?

Auxazalux designed the housing geometry to maintain consistent contact pressure on the factory terminals, preserving electrical continuity for tuner communications. The ABS material resists deformation and vibration-related loosening, which helps keep signal paths stable under normal driving conditions. While no connector can change the tuner’s programming, a secure and low-resistance connection supports reliable data transmission.

• Ergonomic plug shape for accurate alignment and firm contact
• Wear-resistant ABS reduces connector fatigue over time
• Helps maintain original pin alignment and electrical continuity
• Ideal for repeated plug/unplug cycles during tuning work

What should I check before ordering to make sure these plugs fit?

Confirm the number of pins and the physical shape of your existing tuner connector against the images and specs provided. If your truck uses a customized or aftermarket harness that differs from factory connectors, these housings may not match. When in doubt, compare the connector photo on the listing to the harness on your vehicle or consult a trusted technician.

• Match connector pin count and overall housing shape
• Confirm vehicle year and engine model listed above
• Check for aftermarket harness modifications that alter fit
• Keep factory terminals in place during replacement for easiest install

Who is this for?

This Auxazalux tuner harness plug kit is intended for truck owners, diesel mechanics, and performance shops working on late-model Ford F-Series diesel vehicles that need a dependable, no-solder replacement connector. It’s particularly useful when the original housing is cracked, brittle, or no longer holds terminals securely, and for anyone who wants a fast, maintenance-friendly way to restore tuner connectivity while preserving the factory wiring.
