This harness features a firewall mounted Mil-Spec connector. Rywire also offers a Mil-Spec engine harness without this connector available HERE.

When you select your "Vehicle Type", select your vehicle chassis type, not the engine going into the car as this tells us what interior "Chassis Adapter" to use for your setup. If your application is not listed, Rywire can probably make one for you - so please select "other/custom" and we will contact you for the details.  This harness is cross-compatible with any D series or B series engine. 

Each harness will come with a custom back side sub-harness (chassis adapter) 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 engine wire loom!

If you are not using OBD1 injectors, such as OBD2 injectors, RDX injectors, or Injector Dynamics injectors please select "other/custom" on the drop down menu. 

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).

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.
