Rywire 88-91 Honda Civic/CRX Si/HF/EX Chassis Specific Adapter

This Rywire chassis specific adapter uses a 1000-ohm resistor to help prevent check engine lights when swapping in a different engine. It's designed specifically for the 1988-1991 Honda Civic and CRX models, covering Si, HF, and EX trims. This adapter makes integrating a new engine much simpler, bypassing the need to manually rewire or bypass factory sensors that might not match your new powerplant.

Rywire built this adapter to be a direct plug-and-play solution. It connects between your existing chassis harness and the new engine's wiring, ensuring all the necessary signals are communicated correctly. This means you can get your project running without the headache of chasing down electrical gremlins or making complex custom wiring modifications. It’s a well-built piece that takes a lot of the guesswork out of a popular engine swap.
