December 2024 Update: iWire is no longer offering harness merge services so we can focus on other parts of the business, including iDCCD, plug-and-play harnesses, and replacement electrical components. As part of this change, our technical support, wiring guidance, and troubleshooting assistance for harness merge projects will be very limited moving forward.
We appreciate everyone who trusted us with their swap wiring over the years.
These blog posts will remain available as a resource for the Subaru swap community.
To learn more about why we ended our harness merge services, please read the blog post below:

Version means which version of the Subaru Impreza it is. V1 is the first Impreza built, V2 is the second generation, ETC. The Version number was mainly used in JDM Subaru models though they stopped labeling them as V1 or V4 after 2000. If you are importing a JDM engine and the importer calls it a V7, V8, V9, or V10 - make sure to figure out precisely which year of car the engine is coming from. Please take a look here for help determining which engine you have. Please take a look here.
