All Mil-spec engine harnesses are made to order.
We will call you after ordering to finalize and make sure you get the correct harness for your application.
All finalized orders are non-refundable and there is nocancellation.
The quick disconnect Mil-Spec harness features a firewall mounted Mil-Spec connector that will allow easy engine removal for quick engine changes and customization.
The Rywire H-series (H22A/H23A) or F-series (F20B/Accord) Mil-spec tucked engine wire harness is cross-compatible with both engine types.
MUST use internal coil type distributor with this harness. External coil type distributor is not compatible.
This harness uses Mil-Spec Teflon coated wire with a maximum heat rating of 200°C . The Teflon coated wire is loomed with The highest quality Raychem DR-25 heat shrink covering, and adhesive lined wire junctions to keep moisture out. Each connector is crimped with pneumatic heads to ensure an OEM crimp every time, then tagged with a yellow identification labels for easy installation. All heavy interference circuits are protected and grounded with proper wire covering.
All connectors and materials are new. Each connector is crimped with pneumatic heads to ensure an OEM crimp every time, then tagged with a white identification label for easy installation. All heavy interference circuits are protected and grounded with proper wire covering. Our engine harnesses are 100% quality tested pin to pin; And resistance checked to ensure no voltage fluctuations.
All Rywire engine harnesses are made with OBD1 (92-95) ECU Connectors. An ECU adapter can be used for OBD2 ECU's if necessary however our harness does not support USDM OBD2 ECU's. Aftermarket ECU's using OBD2 plugs and Non-US OBD2 ECU's are compatible (except for H22 and GSR stock computers).
Each harness will come with a custom back side sub-harness that will be proprietary to the chassis you choose on the drop down menu. This way if you ever change chassis you will only need a new sub-harness, not a whole new wire loom!
These harnesses are warrantied and guaranteed to work, however they are non-refundable. Because the back-side (interior/shock tower connection) separates from the main harness, the engine harness can be used on multiple chassis provided the engine itself uses the same components. We sell the back-side harness separately only over the phone for previous engine harness customers.
Attention Prelude & Accord owners:
Rywire may need to borrow your stock Prelude/Accord engine harness for reference of the shock tower configuration to complete your harness. This allows for the easy installation we are known for. Some models we have specs for, but the Prelude and Accord models vary so much that we would rather be 100% certain it's an exact match by having your harness to compare to.
