Connect a K-Series engine to a custom chassis with the Hybrid Racing Universal K-Series Swap Conversion Wiring Harness. Intended for builds without a chassis-specific conversion harness.
Designed for custom builds, this harness brings the engine ECU, power supplies, relays, and chassis signals together without requiring a standard Honda body harness. Labeled wiring and new connectors simplify tracing circuits, and the diagnostic port keeps access to engine information after the swap.
