Wiring harness

If you can affordably 3rd party source all the proper ECU, sensor and actuator connectors and pins then fabricating a harness becomes feasable. Until then you will still need a donor harness to physically plug into all the components it take for the motor to run.

Agreed, it is just a lot easier and cheaper to use the Subaru harness, it is not that complicated and is proven to work, why would anyone want to not use it and follow FFR guidance is beyond my comprehension.
