Thanks for the help. As far as I can tell the automatic tranny connectors are the same between ka and sr. I have this Wiring Specialties harness that I believe should be able to cover both the auto > manual and sr20de to sr20det aspects.

Now I'm just searching for install instructions, I can't seem to find any install guide for this particular harness on the wiring specialties website.
