Toyota's factory inverter drops from 400W to 100W the moment you start driving — which is exactly when it shuts your fridge or other gear off. This plug-and-play harness keeps the inverter at a full 400W while the truck is moving, with no splicing and no cutting.
Plug it into the factory inverter under the center console and ground the terminal to a nearby bolt. Each kit includes an optional extension so you can add a second 3-prong outlet up in the cab where it's easier to reach (outlet not included; pair it with a Toyota interior outlet upgrade kit).
Fitment:
- 2005-2023 Toyota Tacoma
- 2010-2024 Toyota 4Runner
- 2007-2014 Toyota FJ Cruiser
- 2022+ Toyota Tundra (non-hybrid)
