Keep your factory inverter operating at full power with this plug-and-play harness designed to maintain 400W output while your vehicle is in motion. Unlike the factory setup that reduces inverter output to 100W once driving begins, this harness allows you to continue powering essential devices such as portable fridges without interruption.
Installation is simple and requires no splicing or permanent modifications. Just plug the harness into the factory inverter located under the center console and attach the ground terminal to a nearby bolt. The straightforward design makes this a quick and clean upgrade for anyone looking to maximize the usability of their factory power system.
Each kit includes an optional extension that allows you to add an additional 3-prong outlet inside the cab for easier access and improved convenience (outlet not included). For the outlet, order Toyota part number 85530-35050-C0 from your local dealer or purchase the complete Outlet Upgrade Kit. With this upgrade, you can fully utilize your factory inverter and keep your devices powered wherever your journey takes you.
