I have a 91 ls powered hatch. I bought the shell from a friend and it was wired for b16. My car always threw a code 9, we replaced the distrubutor and finally decided it was the wiring (the wiring is a mess). I decided to redo it all. I was wondering if ls and Si wiring is the same. I have both wiring diagrams and can't tell much of a difference (I followed all wires and most run to right places besides auto tranny stuff). Any help would be appreciated, thanks.

I think you can get it to work with the si harness I used my civic harness on my LS engine and it worked just fine

you can use the si harness but you have to lengthen a few wires and change i think one or two plugs. just hook everything up and see which ones don't quite reach then lengthen them. also a few plugs can fit in the wrong spots...i did this and couldn't figure it out, so fair warning on that.
