I got very overwhelmed at first with the wiring when I did my swap, but after I looked into it and bought a chilton manual, everything went by really easy. If you dont have a chilton or haynes get one. I'm still a newbie but I will give you the best answers I can. First you will get the conversion harness and on the input side of the harness act like that is your obd2 ecu. I know you will need to add the vtec wire, and you will need to do the 2-wire to 3-wire IACV fix (there are steps to do that on that link I posted). But remember all your wiring will be done to the clips that plug into your conversion harness. You will have to pull the pins out of the stock wire plugs on your wiring harness, and relocate them in the correct pin locations. Hopefully that helps.
