2000 Honda Civic interior wiring problem

I have a 2000 honda civic si body with a 2000 honda ex motor with an automatic transmission. Everything seems to be working. The main wiring harness to the motor seemed to match up perfectly. Now I am having trouble with the interior wiring. Specifically the wiring to the automatic gear shifter. Because the SI had a manual transmission I dont think it has the same wires. Also, I know I have to install the control assembly interlock thing that keeps you from cranking the car while its in gear but I can't figure out where the hookup for that is either or if there is one. I am hoping this is all I have to do but I am not sure about that, either. Can anyone tell me the difference between the ex and si wiring harnesses and hopefully what to do to fix it.

Hi cinkajb,

Auto and manual trans gear shift wiring circuits are different.

Interlock is for prevention of shifting out of park without applying the brakes.

Neutral start is another system which prevents the cranking of the engine except in when gear shift is in park or neutral position.

There are quite a lot of differences so is not going to be easy to resolve.
