I'm planning on doing a conversion from a d15b2 to a d16z6 in my 93 hatch. I know the d15 is ODB0 and z6 is ODB2, so the d15 currently is a dpfi so i bought the ODB0 to ODB1 conversion harness dpfi. So now you know my plans im a little confused with the harness. From the picture below which ive messed around with in MSpaint shows you where im at, Am i right in saying that the pink & red remain unused? So that leaves me with the 3 blue wire's and the 1 brown wire, which i don't know where they go??
