This is our premiere plug n' play harness modification service for your Subaru engine conversion!

You simply supply us with the Subaru harness from your donor car and we return a precise, year/model-specific, plug-and-play harness. All connections are labeled for a quick and easy installation into your conversion.

Harness Service Options:

• Expedited Service: The standard service time is 3 weeks from when we receive your harness. However we also offer a two-week harness turnaround for an additional $250, or if you need your modified harness ASAP we also offer a one-week harness turnaround for an additional $500.
• Drive-by-wire: If you are using a drive-by-wire donor motor there will be an added $100 fee. Please select the appropriate drop-down option if you plan on using drive-by-wire.
• Pre 1995 Donor Cars: If you are planning on using a 1990 - 1994 Subaru donor motor for your conversion please select "yes" under the pre 1995 option. Due to the early model Subaru intake manifold some extra labor is required to ensure your harness is working properly, any pre 1995 Donor harness will have an added $100 fee. 
• Important Notice: If your harness has been previously modified or is in bad shape we may need to add additional labor to your specific harness. In this case, it is an additional $100 per hour of labor, you will be notified before starting the work.  

This Service is for Subaru years 1990-2007, We are currently only accepting U.S harnesses for modifications.
