ECS Tuning Gen3 Wastegate Adapter Harness

Setting up a new turbo shouldn't feel like a wrestling match. If you’ve ever tried to calibrate a wastegate actuator while leaning over a hot engine bay—or worse, tried to hold a gate closed manually while chasing voltage readings—you know the struggle.

The ECS Tuning Wastegate Extension Harness is the "extra set of hands" you’ve been looking for. Designed specifically for enthusiasts who demand a perfect adaptation before the first bolt is even torqued, this harness takes the frustration out of bench testing and installation.

FEATURES

• True Bench Testing: Why wait until the turbo is bolted to the block? Calibrate your wastegate on your workbench with full access to the adjustment nuts.

• Hands-Free Calibration: For IS12 and IS20 models, the integrated alligator clips allow you to power the wastegate to a closed position. Stop fighting the spring tension and focus on your multimeter.

• Extended Reach: With 8 feet of high-quality cabling, you have the freedom to move your turbo anywhere in the bay or over to a nearby workstation without disconnecting from the vehicle’s harness or battery.

• Professional Grade Construction: Built to survive the garage environment using a mix of 16 and 18 gauge wire, fully protected by heat-shrink wrapping for maximum durability and a clean look.

• Secure Connection: Heavy-duty alligator clamps provide a rock-solid connection to your 12V source, ensuring consistent power during the adaptation process.

PRODUCT DEVELOPMENT

Our Wastegate Adapter Harness was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

NOTE: The alligator clip "hold-closed" feature is not required for IS38 models, and is only intended for use on IS12/IS20 turbochargers.
