Seguler Shibby Engineering Tuner Harness Plug Kit for 2008-2025 6.4L 6.7L Ford Powerstroke

FITMENT

• 2008–2025 6.7L Ford F-250 F-350 F-450 Super Duty V8 Diesel.
• This kit is purely a hardware protection solution; it contains zero tuning software, electronics, or performance calibration files.
  
• This base kit covers the primary EGR and Exhaust/DPF plugs. It does NOT include the specialized DEF tank module plugs, Crankcase Ventilation (CCV) caps, or SOTF custom sensor caps (available separately).

DESCRIPTION

Product Overview

• Installing aftermarket custom tuning and hardware modifications on a 6.7L Powerstroke leaves several factory sensor plugs unhooked and unprotected across the engine bay and undercarriage.
• Abandoning these live OEM harness connectors exposed subjects them to relentless road salt, grime, harsh climate conditions, and aggressive underbody washdowns. Left unsealed, moisture and grit gradually penetrate the electrical pins, triggering heavy corrosion, dangerous circuit shorts, and expensive shop diagnostic fees.

Key Features

• Delivers 100% defense against moisture, dust, road grime, and winter salt spray, permanently preventing pin corrosion at every disconnected sensor point
• Built to extreme automotive standards with weatherproof isolation that withstands severe under-hood temperatures, continuous chassis vibration, and high-pressure water exposure
• Comprehensive multi-plug bundle covers engine-bay EGR system connectors and under-frame DPF/exhaust temperature sensor plugs—every critical location addressed
• Shields live factory circuits from electrical interference and ground-loop faults, keeping the original harness intact for a clean future restoration

FAQ

Q: Why do I need a harness plug kit after deleting my Ford Powerstroke?

A: When sensors are removed from the exhaust, open factory wiring sockets are exposed to moisture, road salt, and mud. These plugs keep the electrical contacts dry and clean, preventing short circuits and pin corrosion.

Q: Can these caps prevent parasitic battery drain and CAN-bus communication errors?

A: Yes. Water and road salt bridging the open copper terminals inside unplugged factory connectors can cause mild electrical shorts. This leaks micro-currents and disrupts the vehicle's CAN-bus network, causing erratic dash warnings. These caps eliminate those short circuits completely.

Q: Will installing these caps interfere with aftermarket wiring or SOTF switch harnesses?

A: No. Every cap fits tightly within the footprint of the original factory connector. They do not increase the plug profile, leaving plenty of clearance for aftermarket exhaust hangers, fuel sumps, or SOTF switch wire routing.

Q: My factory harness locking clip was damaged during sensor removal. Will these caps still stay attached?

A: Yes. The caps are precision-machined with internal friction ribs that maintain a tight, weather-tight seal against the connector's internal rubber gasket, even if the outer plastic locking latch on your original harness is cracked.
