Upgrading or swapping the engine in your Acura Integra can significantly boost its performance. However, dealing with the complexities of wiring, especially when adapting to OBD2 systems, can be daunting. The Acura Integra Obd2 Engine Harness from Rywire Motorsport Electronics offers a streamlined solution, designed for enthusiasts and professionals alike.
What exactly is an engine harness, and why is an OBD2-specific option crucial for your Acura Integra? Let’s delve into the details and explore how Rywire’s harness can simplify your engine swap project.
Understanding the Acura Integra OBD2 Engine Harness
An engine harness is essentially the central nervous system of your engine, connecting all vital sensors, actuators, and components to the engine control unit (ECU), or computer. For Acura Integra models, particularly those transitioning to or utilizing OBD2 (On-Board Diagnostics II) systems, a compatible harness is essential. OBD2 is the second generation of on-board diagnostics, offering enhanced engine management and diagnostic capabilities compared to its predecessor, OBD1.
Rywire’s Acura Integra OBD2 engine harness is engineered to provide a plug-and-play solution for various engine setups in Integras. While built with the same high standards as their Mil-spec line, these budget-friendly harnesses utilize a single black wire color and expandable loom, maintaining quality and performance without unnecessary frills.
Key Features and Benefits
Rywire engine harnesses are built with meticulous attention to detail, ensuring reliability and performance. Here are some key features of the Acura Integra OBD2 engine harness:
-
New Connectors and Materials: Only new, high-quality connectors and materials are used, guaranteeing a reliable and long-lasting connection.
-
OEM-Grade Crimping: Each connector is crimped using pneumatic heads, replicating the precise and consistent crimp quality found in OEM (Original Equipment Manufacturer) harnesses.
-
Labeled for Easy Installation: Each connector is tagged with a white identification label, simplifying the installation process and reducing the chance of errors.
-
Protected Circuits: Heavy interference circuits are properly shielded and grounded, minimizing electrical noise and ensuring signal integrity.
-
100% Quality Tested: Every harness undergoes rigorous 100% pin-to-pin quality testing and resistance checks, guaranteeing proper function and eliminating voltage fluctuations.
-
OBD1 Computer Compatibility: Rywire harnesses are made with OBD1 (92-95) computer connectors as a base. This design choice offers versatility, especially for those upgrading older Integras or using aftermarket ECUs.

OBD1 and OBD2 Considerations
It’s crucial to understand the OBD compatibility of this harness. Rywire harnesses are built with OBD1 computer connectors. This means that for Acura Integra OBD2a or OBD2b computers, an adapter must be used. It’s important to note that this harness does not directly support USDM OBD2 computers. However, it is compatible with aftermarket computers using OBD2 plugs and Non-US OBD2 computers (excluding H22 and GSR stock computers). This makes it a versatile choice for engine swaps and modifications, particularly when using performance-oriented aftermarket ECUs.
Modular Design for Flexibility
A standout feature of Rywire harnesses is their modular design. Each harness comes with a custom back-side sub-harness tailored to your chosen chassis. This ingenious design means that if you decide to change your chassis in the future, you won’t need to purchase a completely new engine harness. Instead, you can simply acquire a new sub-harness, offering significant cost savings and flexibility in the long run.
