Rywire Motorsport Electronics

Our D-series & B-Series OBD1 Mil-spec wire harness is cross-compatible with both engine types.

This harness uses Mil-Spec Teflon coated wire with a maximum heat rating of 200°C .Standard wall ethylene-tetrafluoroehtylene (ETFE) insulation ( also known as Tefzel ) designed for aerospace applications where weight, dimensional tolerance, and mechanical durability are required. This wire exhibits high chemical and radiation resistance. 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.

Rywire also offers a Firewall mounted Mil-Spec connector that will allow easy engine removal for quick engine changes and customization. It can be added to any Mil-Spec wire harness.

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) Computer Connectors. A computer plug adapter can be used for OBD2 computers if necessary however our harness does not support USDM OBD2 computers. Aftermarket computers using OBD2 plugs and Non-US OBD2 computer'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.

Chassis adapter options

This harness can plug and play into any chassis, but we recommend our Rywire standalone RACE fuse box http://www.rywire.com/product-p/b-sub-race.htm

This fuse box allows for a quick and easy install into any chassis, off road car, sand rail, buggy, gutted circuit or drag race car.

This harness with the RACE fuse/relay box can also be plug and play with our SWITCH PANEL

The engine harness, fuse/relay box, and switch panel are all PLUG AND PLAY making your life much easier!

MADE IN THE U.S.A.
