Reusable Harness?

[Wangan Wagon]

Hey guys, I was wondering if the wiring harness from my EJ22 BK7 can be used on my EJ22 BK4? The reason I ask is because the ECUs have different numbers and I'm guessing I can't use the ECU without swapping my sensors from the BK7 to the BK4.
It would be nice to have a harness I can splice with an SVX one without having my car down for so long.....

Did you try the different ECU's?

In my fun with different legacys, I have, without changing the wiring,

used a 91 SS 5mt & 91 SS 4eat ECU in an auto 91 SS, along with my 91 5mt ECU in a 92 4EAT car.
Used an auto EJ22E, auto Forester ej25D & manual outback ej25D ecu's in my auto 96 Legacy with both EJ22 & ej25D motor.

Note that each of those ECU's had different part numbers.

Lastly, if you are certain that the wiring is different, then just swap the wiring harness on the motor.
