Enhance the look and performance of your engine with our Budget D-series and B-series compatible wire-tuck engine harness. Designed for enthusiasts who demand both quality and value, this harness offers a streamlined, tucked appearance while maintaining optimal electrical conductivity and reliability for your Obd2 Engine setup. While economically priced, it shares many premium features with our Mil-spec line, making it an excellent choice for your project car.
Key Features of Our OBD2 Engine Harness
Our wire-tuck engine harness is meticulously crafted with new, high-quality connectors and materials. Each connection is pneumatically crimped to meet OEM standards, ensuring a secure and lasting connection for every wire in your OBD2 engine system. For ease of installation, each connector is clearly tagged with a white identification label, simplifying the process and reducing the chance of errors. Circuits prone to interference are shielded and grounded with robust wire covering, providing enhanced protection and signal integrity for your OBD2 engine‘s critical sensors and components. Furthermore, every engine harness undergoes rigorous 100% pin-to-pin quality testing and resistance checks, guaranteeing consistent performance and eliminating potential voltage fluctuations that could impact your OBD2 engine‘s operation.
OBD Compatibility and Adaptability
It’s important to note that all Rywire engine harnesses are built with OBD1 (92-95) computer connectors as a base. This design offers broad compatibility and is easily adaptable for OBD2 engine management systems. To use our harness with OBD2a or OBD2b computers, a simple adapter is required, offering a flexible solution for various Honda and Acura models. Our harness is specifically designed to be compatible with aftermarket computers utilizing OBD2 plugs and Non-US OBD2 computers (excluding H22 and GSR stock computers). Regrettably, our standard harness does not directly support USDM OBD2 computers without the use of appropriate adapters and potentially aftermarket ECU solutions.
Modular Design for Chassis Flexibility
Each harness includes a custom back-side sub-harness tailored to your chosen chassis, selectable from our drop-down menu during purchase. This innovative modular design means that if you decide to change your vehicle chassis in the future, you won’t need to replace the entire wire loom. Instead, you can simply acquire a new sub-harness, saving both time and money. This feature makes our engine harness a versatile and future-proof investment for your OBD2 engine projects.
