Confirm Compatibility

Use the collection title, product application details, and vehicle or ECU options to narrow the correct wiring solution. If your chassis, engine, ECU, or swap combination is not clearly listed, contact VTI before ordering.

VTI-Built vs Partner Products

Products manufactured by VTI Motorsports are identified in their individual listings. Partner and vendor products remain available where they support a complete wiring or ECU installation.

Custom Configurations

For combinations outside the production catalog, submit a custom harness request with the chassis, engine, ECU, trigger system, injector type, and required sensors or auxiliary functions.
