Rywire offers a budget-friendly engine harness compatible with D-series engines in Honda Civics, facilitating OBD1 to OBD2 conversion. This harness allows for a simplified engine bay aesthetic with its tucked design and boasts features comparable to military-spec harnesses. Understanding the harness options and compatibility is crucial for a successful engine swap or upgrade.
Rywire Engine Harness: Features and Compatibility
Rywire’s engine harnesses are designed for durability and reliability using new connectors and materials. Each connection is pneumatically crimped for an OEM-quality connection and labeled for easy installation. Shielding protects critical circuits from interference and ensures proper grounding. Rigorous quality control includes 100% pin-to-pin testing and resistance checks to eliminate voltage fluctuations.
Critically, these harnesses are built with OBD1 (92-95) computer connectors. Adapting to OBD2a or OBD2b ECUs requires a separate adapter harness. Note: USDM OBD2 computers are not supported. However, the harness is compatible with aftermarket ECUs using OBD2 connectors and non-USDM OBD2 computers (excluding stock H22 and GSR computers).
Simplifying Chassis Swaps with Interchangeable Sub-Harnesses
Rywire simplifies the process of changing chassis by incorporating a custom, detachable sub-harness specific to your chosen chassis. This allows for reusing the main engine harness across different chassis, requiring only a new sub-harness for compatibility. Should you change your chassis, contact Rywire directly to purchase a new sub-harness. This modular design offers flexibility and long-term cost savings. These harnesses are warrantied for functionality but are non-refundable due to their custom nature.
