Our
H (H22/H23) or F (F20B/Accord) Series Mil-spec tucked engine wire harness is cross-compatible with both engine types.
The distributor connections are setup for internal coil distributors only. CAN NOT USE EXTERNAL COIL.
PLEASE NOTE: This harness will still be offered, however some changes will be made moving forward:
Because of low demand, and soaring material prices, we are forced to make adjustments to
our B/D series harnesses converting them to H/F series specs.
The harnesses are quite similar, so the fitment is very very close.
-If you select an injector resistor box, one will be installed for you near the orange power service plug.
-Desired injectors will still be installed normally.
-Alternator will be pinned to a generic 3 pin connector and lengthened from the back of the
engine to the front of the engine. (H22a factory location)
-Mating connector for the transmission reverse lamp connector will be supplied.
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 adapter can be used for OBD2 computer's if necessary however our harness does not support USDM OBD2 computer's. Aftermarket computer's 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
http://www.rywire.com/product-p/ry-switch-6.htm
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.

Attention Accord and Prelude owners:We 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.
