We are proud to manufacture one of the only and best solutions for the missing AVCS Bulkhead wiring. This is a must for any JDM motor conversion. Our kit uses factory terminal pins so each part simply clips into place in the Bulkhead harness, thus completing the run of wires from the ECU to the Engine Bay's Black, Brown, and Grey connectors. A full 4 page install guide is also included. This is an Add-On harness to the stock Bulkhead Harness. It does not require cutting, splicing, and is completely reversible.
The AVCS Bulkhead kit is intended for the following setups:
US Impreza WRX 2002-2005 with a complete factory bulkhead wiring harness
JDM ver7/8/9 ECU
JDM ver7/8/9 Motor w/ JDM Engine wiring harness
Everything will be plug and play if the above items are met. We can do custom AVCS kits for those running Hydra EMS with JDM and USDM motors. Simply contact us for more details, custom wiring fee may apply.
Bulkhead Harness = the large harness that runs from the ECU, across the firewall, and ultimately out to the Black/Brown plugs at the battery as well as the Grey plug on the passenger side strut tower. The Bulkhead harness terminates in the engine bay and ultimately connects to the Engine Harness. Every US 2002-2005 WRX comes with a bulkhead harness from the factory, but the US cars do not include the bulkhead AVCS wiring, that is where our kit comes into play.
Engine Harness = the Engine Harness continues where the Bulkhead Harness stops. The Engine Harness connects to the coil packs, injectors, throttle body, etc. It resides underneath the intake manifold and has 3 main male plugs to it: Black, Brown, and Grey. The JDM ver7-9 motors will have the exact same plugs. If, for some reason, the JDM motor has the plugs cut off (or the entire Engine Harness is missing) then you will want to purchase our AVCS Engine Harness which will convert your Stock US ej205 Engine Harness into a JDM Engine Harness.
Attention Right Hand Drive Customers
When purchasing the AVCS Bulkhead harness, be sure to select the correct model type since the wiring lengths are different between Left to Right Hand Drive.
