Re: obd2 gsr in 93 civic si
Plug everything in via your stock harness. Rewire the plug for the alternator. You can either buy a sandwich harness for the distributor if you're not comfortable with wiring....or do the distrbutor rewire yourself. Remember to solder the connections. If you're planning on using butt connectors and tape, just buy the conversion harness.
You'll need to make a knock sensor sub harness depending on what ECU you use. Don't break the knock sensor when you unplug it or plug it in. It's very easy to break.
You also need to wire the IAB if you want the IAB to work.

Re: obd2 gsr in 93 civic si
If you use an OBD2 integra engine harness the whole thing is plug and play, simply use an OBD1 ECU and wire knock back to the ECU if you're use an ECU that looks for a knock sensor. You will need to wire vtec from the solenoid to shock tower plugs if using an LS harness. If using a GS-R or ITR harness it's obviously already there.

Most of the OBD1 vtec ECUs look for knock. P30, P61, P72, PR3, Some PW0s (the Euro ones don't), P13.
P28, P07 and Euro PW0 ECUs are the only ones I can think of right off that don't look for a knock sensor.

Re: obd2 gsr in 93 civic si
No, it wont look for one, it doesn't have the circuitry to operate the secondary butterflies in the intake so there's no point in wiring those either.
The brackets for the power steering pump. You need the A/C bracket from a '97 - '01 CR-V, everything else you reuse from the civic.
