Rywire RY-H2-MILSPEC-DA-EARLY Honda F/H-Series Mil-Spec Engine Harness OBD2 with Integra DA Adapter

The Rywire RY-H2-MILSPEC-DA-EARLY is a professional-grade Mil-Spec engine harness designed for Honda F-Series (F20B/Accord) and H-Series (H22/H23) engine swaps into 1990-1991 Integra DA chassis. This harness is cross-compatible with both engine types and features OBD2 distributor, injector, and alternator connectors paired with OBD1 (1992-1995) ECU plugs.

Key Features:

• Made in the USA with mil-spec Teflon-coated wire rated to 200°C maximum heat
• Features ETFE (Tefzel) insulation designed for aerospace applications with superior chemical and radiation resistance
• Loomed with high-quality Raychem DR-25 heat shrink covering and adhesive-lined wire junctions for moisture protection
• All connectors pneumatically crimped to OEM standards and labeled with white identification tags for easy installation
• 100% quality tested pin-to-pin with resistance checking to ensure no voltage fluctuations
• Includes chassis-specific sub-harness for 1990-1991 Integra DA (replaceable if chassis changes)
• Internal coil-type distributors required; external coil distributors not supported
• Compatible with aftermarket ECUs using OBD2 plugs and non-USDM OBD2 computers (excludes H22 and GSR stock computers)

The modular design allows the back-side (interior/shock tower connection) to separate from the main harness, enabling use across multiple chassis provided the engine components remain the same. All heavy interference circuits are properly protected and grounded. This harness is warrantied and guaranteed to work, though it is non-refundable.
