Are you looking to enhance the aesthetics and performance of your engine bay while ensuring reliable electrical connections for your Obd2 Engine? The Rywire Budget D-series and B-series compatible wire-tuck engine harness offers a nearly identical quality to our Mil-spec line, but at a more accessible price point. The main difference lies in the single black wire color and the expandable loom used, without compromising on the quality of connectors and crucial functionalities.
Please review the options available carefully to ensure you select the correct parts for your specific needs. We understand the importance of precision in automotive wiring, which is why all connectors and materials used in our harnesses are brand new. Each connector is crimped using pneumatic heads, guaranteeing an OEM-level crimp every single time. For easy installation, each connector is tagged with a white identification label, streamlining the setup process. To protect against electrical interference, all heavy interference circuits are properly shielded and grounded with robust wire covering. Every Rywire engine harness undergoes rigorous 100% quality testing, including pin-to-pin checks and resistance testing, to eliminate any potential voltage fluctuations and ensure peak performance and reliability for your OBD2 engine.
Important Compatibility Information for OBD2 Engines:
It is crucial to note that all Rywire engine harnesses are built with OBD1 (92-95) Computer Connectors. This design choice ensures broad compatibility and high performance. If you are using an OBD2a or OBD2b computer, you will need to use a computer adapter. Our standard harness is not compatible with USDM OBD2 computers. However, it is fully compatible with aftermarket computers utilizing OBD2 plugs, as well as Non-US OBD2 computers (excluding H22 and GSR stock computers). This compatibility makes our harness a versatile solution for a range of engine management systems in OBD2 engine setups.
To enhance the versatility and longevity of your engine harness system, each Rywire harness includes a custom back-side sub-harness. This sub-harness is specifically designed for the chassis you select from our options. This innovative feature means that if you decide to change your chassis in the future, you will only need to replace the sub-harness, rather than the entire wire loom, saving you time and money.
We stand behind the quality and performance of our harnesses. These harnesses are warrantied and guaranteed to be fully functional. However, please be aware that they are non-refundable due to their specialized nature. The modular design, with a separable back-side (interior/shock tower connection) from the main harness, allows the engine harness to be adaptable to different chassis, as long as the engine components remain consistent. For customers who have previously purchased an engine harness and require a replacement back-side harness, we offer these separately, available for order over the phone.
