Connect the chassis wiring in your 1988–1991 Civic or CRX to a supported K-Series engine harness and ECU with the Hybrid Racing conversion harness.
The conversion harness is the link between the original body wiring, K-Series engine harness, and ECU. New factory-style connectors and labeled wiring simplify installation without relying on aged donor connectors, and the diagnostic connections help make the completed swap serviceable.
