Unlock full control of your rear window anytime, without turning the key.

This Always-On Rear Window Switch Harness Kit is a 100% plug-and-play solution for 3rd gen Toyota 4Runners, allowing you to roll the rear window down whenever you want, engine on or off. No splicing. No cutting. No guessing.

This harness uses OEM-style connectors that plug directly into the factory wiring and piggy-backs off the original connectors. There is absolutely no cutting or splicing of factory wires required. Your original wiring remains fully intact and reversible.

Problem: Splicing into OEM wiring is unreliable, can cause intermittent failures over time, and permanently damages factory wiring. This harness avoids all of that by plugging straight into the original connectors the way it should.

The extra-long harness measures over 130 inches, giving you the freedom to mount the included switch virtually anywhere in the rear of the vehicle. Our favorite location is near the rear 12V outlet, but the length allows for many clean mounting options depending on your setup.

Installation is extremely simple. Just unplug the factory connectors, plug this harness in-line, mount the switch, and secure the wiring using the included zip ties. No special tools or wiring experience required.
