WRONG

The HF and STD ENGINE harnesses are different than the SI and DX. What the difference is, I'm not sure, but this is what I've heard from a reliable source.

Try to figure out how to convert it yourself and save yourself the money. I've got a JDM Si wire harness that is OBD0. You can combine this with your OBD1 Si harness, change a few clips, and it SHOULD hook right up...meet up with me and i"ll give it to you for liek 5$ (gas for me to meet you somewhere) cuz I have no use for it.
