Seguler Shibby Engineering Tuner Harness Plug Kit for 2011-2014 6.7L Ford Powerstroke
Product Overview
Q: How hard is it to pop these caps off later if I want to go back to stock?
A: Very easy. The caps use the same OEM-style quick-release tabs, so they lock onto the harness tight but can be pressed and pulled off in seconds — the factory wiring stays 100% untouched and ready for the original sensors.
Q: Couldn’t I just cover the open plugs with electrical tape and call it done?
A: Tape is a short-term fix that backfires. Under engine heat, oil, and road salt it breaks down, and once the adhesive lets go it actually holds moisture against the pins — corroding them faster than leaving them bare. These caps make a permanent, airtight seal that keeps water out for good.
Q: Does this kit also fit a 2015 Ford 6.7L Powerstroke?
A: No. Ford changed the wiring, pin counts, and connector shapes on the 6.7L Powerstroke from the 2015 model year onward, and this kit is pinned for the 2011–2014 connector profiles specifically.
Q: Is this kit compatible with Cab & Chassis (F-450/F-550) trucks?
A: It is. The kit fits standard pickups and chassis cab models equally, since the under-hood EGR and the main under-chassis exhaust plugs are the same. Just keep in mind that chassis cabs run different wheelbases and commercial frames, so any extra plugs a body builder added won’t be covered.
