Cover unused connectors on your 6.7L Powerstroke
These harness caps are intended for connectors left unused after the relevant exhaust or EGR modifications. They provide a fitted barrier against water and debris at the unused connection points. They are protective caps, not a tuning device.
Choose the correct year group
| Engine and vehicle years | Selector group |
|---|---|
| 6.7L Ford Powerstroke, 2011–2014 | 2011–2014 |

Match the year group as well as the product option. The listing includes Shibby Engineering and JS Speed Diesel alternatives; confirm the selected kit against the connectors present on your vehicle.
What the caps do
- Close off the unused harness ends covered by the selected kit.
- Use moulded, weather-resistant housings that engage with the matching connector.
- Help keep disconnected wiring organised during an appropriate vehicle modification.
Items outside this package
DEF tank plugs and shift-on-the-fly tuning caps are not included. Check those requirements separately when planning the rest of the build.
Installation considerations
The caps use a snap-in connection. Identify each unused connector and match its shape to the correct cap before fitting. A cap should not be forced onto a different connector, and this kit does not replace repairs to damaged wiring.
Questions about harness protection
Does this kit change the truck's calibration?
No. Its purpose is to cover unused electrical connections. Any calibration requirements must be addressed separately.
Can I order by engine size alone?
No. The four year groups are separate selections. Check the model year and required connector coverage too.
Is every disconnected plug covered?
Only the connector locations served by the selected kit are covered. In particular, arrange DEF tank and shift-on-the-fly caps separately if your build needs them.
