Rywire offers a Mil-Spec OBD1 engine harness compatible with Honda D-series and B-series engines. This high-quality harness, made in the USA, uses Teflon-coated wire rated for 200°C, ensuring durability and performance in high-heat environments. While similar to our Mil-spec line, it features a single black wire color and expandable loom for a clean, tucked appearance.
Choosing the Right OBD2 to OBD1 Harness
Several options are available to ensure a perfect fit for your Honda engine swap. Careful selection is crucial for proper functionality.
Vehicle Type and Chassis Adapter
Specify your vehicle’s chassis type to determine the correct interior chassis adapter for seamless integration with your existing wiring. This ensures compatibility between the engine harness and your vehicle’s interior components.
Injector and Distributor Adapters
If converting from OBD2 to OBD1, you may need specific adapters for your injectors and distributor. Select the appropriate adapters based on your current setup. Consult our injector type list if you’re unsure which adapters you need. Rywire offers a comprehensive selection to accommodate various injector types. For distributor conversions, ensure you choose the correct adapter for a smooth transition to OBD1.
Alternator Considerations for OBD Conversions
Currently, only OBD0/1 to OBD2 alternator adapters are available. If using an OBD1 alternator, select the OBD1 engine harness and use adapters for the injectors and distributor as needed. This ensures compatibility between your alternator and the chosen harness. Plan your alternator setup carefully when performing an engine swap.
Charge Harness Options
The non-separated charge harness option integrates the starter and alternator leads into the fuse box. This is recommended if you’re not using a custom alternator power lead, adding $45 to the base price. This simplifies wiring and ensures proper power delivery to essential components. For relocated batteries, our starter fuse box lead allows you to power the fuse box by simply running a heavy-gauge wire from the battery’s positive terminal to the starter. This provides a straightforward solution for custom battery placements.
