Anytime you do an engine swap with a JDM AVCS Engine into a USDM non AVCS chassis you will need this wiring kit to make it work. You will need to utilize the JDM ECU to make the AVCS work properly.


This kit is designed to replicate the body wiring needed when you install a 2001-2005 JDM WRX (EJ205) or JDM STi (EJ207) engine with AVCS into a 2002-2005 USDM WRX.


The iWire AVCS Bulkhead Wiring Kit is built with Tefzel wire to create the best connection possible and sleeved in Raychem DR-25 that can withstand the heat of the engine bay which means our AVCS harness is smaller, lighter, more flexible, and tougher than any other on the market. Every kit includes a set of full install instructions.


The AVCS Wiring Kit comes with a few options:

Bulkhead Basic Kit includes the wires but you do the pinning for the engine and ECU plugs with help from our instruction manual.

Basic Kit with Locks includes the replacement locks for the Cam Crank Knock (Orange Lock) and Main Engine Plug (White Lock). These are commonly broken when pinning the AVCS during installation so iWire has included the locks at a reduced cost!
