One says NO, the other says YES, but you'll get a check engine light.


Doesn't look good.


Gonz.

The Unichip will work with all years of the WRX, however I do *NOT* reccomend that the TXS harness be used. Something about exposed contacts in a metal rich eviroment like between the ECU and the kickplate sounds... well... stupid.

Have it professionaly wired in, or step up to a Dastek sourced Harness. Rallitek or Dynamispeed are vendors here and can sell you one.
