Product Details
If you're swapping a B or D-series engine into your early EF chassis Honda Civic, getting the wiring sorted is a critical step. This Rywire Mil-Spec engine harness is built to make that process as straightforward as possible, ensuring all your engine components communicate correctly with the chassis. It's designed to integrate seamlessly, so you can focus on getting your project on the road.
Rywire uses Mil-Spec connectors, which are known for their durability and reliability in demanding environments. This means you get a solid connection that resists vibration and the elements, crucial for keeping your engine running smoothly. The harness includes a chassis-specific adapter, meaning it's pre-configured to plug directly into your early EF chassis harness without extensive modification. This saves you a lot of guesswork and potential headaches during the installation. The wiring itself is high-strand count wire, which is flexible and resistant to fatigue, ensuring long-term performance. Every harness is meticulously assembled to meet Rywire's high standards.
This harness is designed to connect your engine's essential sensors and actuators, including fuel injectors, ignition coil, oil pressure sender, and more, to the factory ECU location. It's a well-built component that simplifies a complex part of engine swapping. Make sure to consult your vehicle's service manual and the manufacturer's installation guide for specific connection details and any other components you might need for your swap.
