If you're swapping an AEM Infinity ECU into your 1990-1991 Honda Civic or CRX DX/STD model, this chassis-specific adapter harness from Rywire is what you need. It's designed to connect your AEM Infinity ECU directly to your car's factory wiring harness, making the integration much simpler. This adapter takes the guesswork out of wiring the ECU, so you can focus on tuning your engine.

Rywire builds these harnesses with solid connections to ensure reliable data transfer between your ECU and the rest of your car's systems.
