Subaru EZ-Flash Test Connector Button

If you've ever reflashed a Subaru, you know the pain of digging under the dashboard to plug in those green test connectors—it's a hassle for your hands, your back, and your patience.

The Subaru EZ-Flash Test Connector Button eliminates that headache by plugging directly into the factory green test mode connectors, giving you a convenient, latching button to enable test mode with a single press. No more fumbling under the dash or risking damage to factory wiring—just install it once and flash whenever you need.

Perfect for tuning shops, engine swaps, or DIY tuners who want a clean, functional, and frustration-free solution.
