    You probably would be better off getting a dx harness that hasnt been all hacked up. Then go to www.rywire.com and buy the obd0-obd1 conversion harness. Follow the instructions that come with the harness. It will have leads for the four wire o2 and vtec, you will just have to run the wires and rob a few plugs off a donor harness. If your car is the dpfi you will have to do the mpfi conversion first. You can search and find good write ups on that.

    Did you find a mpfi harness, or did the car originally come with one? If the car was not originally mpfi you cannot just simply replace the harness with a mpfi one it wont work. If that is the case you need to find another dx harness and do the conversion.

    your going to have to do the obd0-obd1 conversion on your harness, and get and obd0-obd1 ecu jumper. and a vtec subharness.

    also you will need the 0bd1 ecu, (im assuming you meant the d16z6 not the sohc zc, because im 90% sure the ZC's are not vtec), which would be the p28
