DIY Harness Modification Kit

DIY Harness Modification Kit

Subaru ECU #22611____?
In stock

This kit enables a person with some wiring ability and lots of time to take a Subaru "bulkhead" wiring harness, remove many connectors and wires, splice and add some wiring and end up with what is necessary to run an engine in another vehicle. These wiring kits are unique to each Subaru year and model. Please note that this kit is a guide for harness modification and not a step-by-step manual. The expected time commitment to convert a harness is 20-40 hours for the first timer.

Also available is the Interface Board for OBDII engines to help eliminate seven common fault codes. 


The Wiring Kit Includes the Following:

  • Identification of needed connectors in the harness
  • Pinout for the ECU with normal voltages and wire colors 
  • Pre-printed labels for ECU connectors 
  • Identification of unneeded wires to cut and tape off 
  • Wire labels and instructions for connecting to the vehicle 
  • Original Subaru wiring diagram for year and model requested 
  • General instructions 

Vehicle wire connections provided are for 1983-1991 Vanagons. All other vehicles please use this instruction as a guide and refer to your vehicle’s wiring diagram.

These kits cannot be returned or exchanged. Please make sure you provide us with the correct year and model of your harness and ECU when ordering.
