• Includes chassis-specific adapter sub-harness for 1988-1989 Civic/CRX DX/STD models
• Single black wire color with expandable loom for cost-effective performance
• All new connectors crimped with pneumatic heads for OEM-quality connections
• White identification labels on each connector for easy installation
• 100% quality tested pin-to-pin with resistance checking to prevent voltage fluctuations
• Heavy interference circuits protected and properly grounded
• Made with OBD1 (1992-1995) computer connectors
• Modular design allows reuse with different chassis by replacing only the sub-harness

This harness delivers nearly identical performance to Rywire's Mil-Spec line at a more accessible price point. The primary differences are the single-color wire construction and expandable loom instead of multi-colored Mil-Spec wire and premium heat shrink. All harnesses are made in the USA and backed by Rywire's quality guarantee.

Note: Charge harness, injector adapters, alternator adapters, and distributor adapters are sold separately and may be required depending on your specific engine configuration.
