What Wire Harness

[CharlieP216]

So I've been working on a project for a while. A 2000 HX with a 95 SirII engine and have a dilemma of sorts. I have a 2000 Si ECU and was going to use my HX harness (it WAS auto, but I've done most of the modding to convert to manual already) well apparently it doesn't work. My HX engine blew back in June and I'm thinking that part of the harness was killed.

Moving on.... Do I specifically need an Si harness? Or can I use any OBD2 harness for 96-00 civic?

Thanks in advance

Just to add to it, I did use the search function and did not find the info I was looking for. I know by now I should of just gotten rid of it and got a manual but I'm too attached to the car.
