  • Description

This conversion will make your Honda Accord or Prelude wiring harness compatible with an H-Series engine.

All Mil-Spec wire harnesses are made with OBD1 (92-95) ECU Connectors attached. We only support Internal coil distributors on H-Series Swaps. You can install any OBD1 coil into your External coil USDM H-Series distributor with very little modification.

*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. For 92-96 BB Preludes you will receive a flying lead for the two wire (coil power/ starter motor) plug on your firewall.

This H (H22/H23) or F (F20B/Accord) Mil-spec wire harness is cross-compatible with both engine types.

The distributor connections are setup for internal coil distributors only. CAN NOT USE EXTERNAL COIL.

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. 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.
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 our engine harnesses are made with OBD1 (92-95) Computer Connectors. A Computer adapter can be used for OBD2A 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!

Component Type:
This option tells us which type of Injector, Distributor and Alternator plugs to put on your harness. We do not mix-and-match these plugs.

Mil-spec Quick Disconnect plug: Would you like to add this? if so, select it for $350 extra.
Our harness does not come standard with this separation plug.

Vehicle Type: Select your vehicles chassis type.
This tells us what interior subharness to use for your setup.

OBD2a ECU: If you would like to run this, this option will need a OBD1 to OBD2a ECU adapter

Charge Harness:
The "non-separated charge harness" option will add the Starter wire if you're relocating your fuse box inside the cabin and no longer using your factory 'battery -> starter -> fusebox' cable.We Also have the "Separated charge harness" which is ideal with the quick-disconnect option.

Please Note that we only do harness for M/T Swaps. H-Series Swap Harness' are compatible with the following OBD1 ECU's: P28/ P30/ P72 (with Hondata). Other ECU's may require further harness modification or may not be compatible.

Accord CG Note: We can only provide a chassis specific adapter for the 98-99 Accord, 00-02 Accords will work however you will have to manually wire a coolant temp gauge. The 00-02 Accord sensor and gauge are unique and will not work with this harness.

Note: These harnesses are warrantied and guaranteed to work, we provide installation support and troubleshooting. However our engine harnesses are non-refundable, returnable or exchangeable. Please make sure that you order the correct wiring harness for your application. If you are unsure of what you need, please contact us before ordering.
