Product Overview
-
When upgrading your 2009-2012 6.7L Cummins, unplugged factory wiring connectors are exposed to moisture, dirt, and engine heat, leading to corrosion and electrical failures over time.

- The Tuner Harness Plug Kit high-impact plugs lock out moisture and dirt to protect your truck’s electrical system and maintain a clean, professional engine bay and chassis layout.

FAQ
Q: Why do I need tuner harness plugs on my 09.5-12 truck?
A: After tuning or removing factory components, some OEM electrical connectors may no longer be used. These protective plugs help seal unused connectors from moisture, dirt, road debris, and corrosion.
Q: Does this base kit include DEF tank plugs or SOTF (Shift-On-The-Fly) switch plugs?
A: No. This base kit includes all required caps for under-hood EGR and under-chassis exhaust sensors. It does not include DEF tank connection caps or SOTF switch wiring plugs.
Q: Are these reusable?
A: Yes. The plugs can be removed and reinstalled if factory components need to be serviced or reconnected in the future.
Q: Do these plugs replace factory connectors?
A: No. These are protective covers only and are installed onto existing factory connectors without cutting or modifying the wiring harness.
