i just bought a conversion harness off of ebay got it today.. its to switch my obd0-obd1. plugged it in and hooked up the obd1 distributer but still nothing. didnt hook up any of the free wires for the o2sensor or nething. could that be the problem. cuz it said to hook up the (iab sensor). still new that this conversion stuff. i got a d16z6 in my 89 civic hb but the only ecu i could find was the p07 could that also be the problem. any insight would greatly be appriciated.
