I know that the procedure has been dealt with several times, but I can't find a good listing of compatibilities. I have a MY04 RS that I'd like a stock 3 spoke from an 05 WRX or maybe even an STi. Will I have harness differences? Maybe if someone knows, they can post a list of MY wheel compatibilities (specifically ones that require nothing more than swapping wheels, no cc or airbag shinanigans).

Thanks,
Phil
