Honda H-Series / H2B Budget Harness Kits – Carrot Top Tuning

Explore budget-friendly Honda H-Series / H2B tucked engine harness kits from Carrot Top Tuning, supplied by VTI. These supplier-built kits are separate from VTI’s handmade Mil-Spec engine looms.

Match your H2B swap to the correct kit

Choose from the Civic EG/EJ, Civic EK and Integra DC applications listed below. Confirm the chassis year, engine setup, ECU generation, injector connectors and included subharness on the individual listing before ordering. An H-Series or H2B label does not establish compatibility with every F-Series engine or standalone ECU.

Availability varies by kit and selected option; check the product page for current stock.

VTI handmade engine-loom alternatives

For VTI-built wiring, browse our in-house engine harnesses, including the Honda H/B-Series OBD1 loom for P28 / Hondata S300 and the Link G4X CivicLink HC96X / Honda OBD2A loom. Each has its own fitment and configuration requirements.

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.
