Product Description

The Rywire RY-B-SUB-EF-DX-LATE Chassis Adapter is engineered to bridge the gap between Rywire's B-Series Budget or Mil-Spec engine harnesses and the stock wiring harness of **1990-1991 Honda Civic and CRX DX/STD models**. This adapter enables a clean, plug-in approach to B-Series engine swaps, retaining the interior harness and avoiding cutting or splicing of factory wires. It maintains the E-plug and associated signal functions crucial for proper operation of electrical systems when using aftermarket wiring solutions. 

Manufactured in the U.S.A., this adapter harness is a critical component when installing Rywire engine harnesses into classic Honda chassis, helping preserve original wiring integrity and simplifying installation. The harness seamlessly connects to the interior wiring of the chassis while the engine harness (sold separately) handles the engine bay connections. Ideal for enthusiasts performing B-Series conversions into early Civics and CRXs, it delivers a professional-grade electrical interface solution.
