Honda OBD2A Wiring

Honda OBD2A wiring solutions for mid-1990s Civic, Integra and related applications. Shop VTI chassis and engine harnessing plus compatible conversion and ECU integration components.

Confirm the chassis year and ECU connector generation before ordering—OBD2A and OBD2B hardware are not interchangeable simply because both are OBD2.

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.
