ok I got myself in a mess tryn to make my 1995 imreza a 2.2T and I had a ej1.8 in it . I had to use the 1.8 harness and throttle body and fuel and vacuum rail. and used the 2.2t intake. problem is i dont know where the vacuum line go because i didnt mark them and now i dont know what sensors are which i tried lookin in a repaire manual but the diagram is to small to follow, here are the some pics.Help:banghead:

The 1.8 harness will not run the 2.2T. It has no provision for running the turbo and has NO knock sensor support at all. It will not understand the larger injectors, etc. With all the differences in the 1.8 ECU and harness it's really not a good choice. You need a stand-alone or use the 22T harness and ECU.
