Rywire Honda B-Series NA w/Syvecs SV+ Eng Harn (4 Inj No EMAP/Boost/ Adapter Req / Drop Ship Only)

This Rywire engine harness is built with a specific focus on naturally aspirated Honda B-series engines running a Syvecs SV+ standalone ECU. It's designed to handle up to four fuel injectors, giving you the flexibility needed for precise fuel control in performance builds. The harness omits EMAP and boost sensor inputs, streamlining the wiring for naturally aspirated setups where those sensors aren't required, which can simplify installation and reduce potential points of failure.

Rywire is known for creating well-built harnesses that make complex engine swaps and standalone ECU installations more manageable. This particular harness uses high-quality materials and construction techniques to ensure reliable connections and durability under the hood. The design prioritizes a clean installation, integrating seamlessly with the Syvecs SV+ ECU to minimize the need for custom adapter harnesses or extensive modifications. This means you can spend less time wrestling with wiring and more time tuning your engine.

When installing a standalone ECU like the Syvecs SV+, a proper engine harness is crucial for reliable operation. This Rywire harness is a direct replacement for the factory harness, designed to plug directly into your B-series engine and the Syvecs ECU. It's important to note that this harness is a drop-ship item, meaning it ships directly from the manufacturer, so please allow for extended delivery times. Ensure your B-series engine is naturally aspirated and you are using a Syvecs SV+ ECU to confirm compatibility.
