i'm planning on doing this swap and just what to know what i would need or need to change to make it run obd1. will i need to do any other wiring if the car the cars has vtec already? if i put it in a non vtec hatch how should the vtec wiring be done? any diagram of the wiring will be great.

 

you would need a obd1 vtec wiring harness for an GSR

 

That is incorrect.

You can use the ITR harness. It will plug directly into your civic chassis harness.
If your civic is already wired for vtec, drop the motor in, plug in a rechipped p28 ecu, and go.
That's it.



Edit: This is assuming you have a 5th gen civic. It will be different for a 6th gen.
