Rywire offers budget-friendly and Mil-spec engine harnesses tailored for D-series and B-series engines. These harnesses are designed with versatility in mind, notably featuring an OBD2 alternator plug type despite utilizing OBD1 (92-95) computer connectors. This design choice caters to a broad range of engine setups while maintaining high-quality connections and materials.
Understanding OBD1 Harnesses with OBD2 Alternator Compatibility
All Rywire engine harnesses are manufactured with OBD1 computer connectors, ensuring compatibility with 92-95 ECU systems. However, to accommodate various alternator types and engine configurations, they incorporate an OBD2 alternator plug. This means while the main computer connection is OBD1, the harness is ready to interface with OBD2 alternators.
It’s important to note that these harnesses are primarily designed for aftermarket computers or Non-US OBD2 computers. USDM OBD2 computers are not directly supported without adapters. For users requiring OBD2a or OBD2b computer compatibility, computer adapters are necessary. This configuration provides flexibility for engine swaps and modifications, allowing for a modern alternator on older OBD1-based systems.
Key Features and Connector Highlights
Rywire engine harnesses are built with meticulous attention to detail. Each connector is crimped using pneumatic heads to ensure an OEM-grade crimp, and clearly labeled for straightforward installation. Circuits prone to interference are properly shielded and grounded. Every harness undergoes 100% quality testing, including pin-to-pin and resistance checks, guaranteeing reliable performance and preventing voltage fluctuations.
The harness connector list includes essential sensors and components, explicitly featuring:
- OBD2 Alternator Plug type
- OBD2 Injectors 1-4
- OBD2 10-pin Distributor plug
- OBD1 Computer Plugs A, B, D
This combination of OBD1 and OBD2 elements within the harness design provides a versatile solution for engine wiring, especially when addressing Obd1 To Obd2 Alternator Wiring needs.
Chassis-Specific Sub-Harness and Installation Guides
Each Rywire engine harness includes a custom back-side sub-harness, tailored to your chosen chassis. This modular design simplifies chassis changes in the future, requiring only a sub-harness replacement, not a complete wiring overhaul. The harnesses are warrantied to function correctly but are non-refundable due to their custom nature.
