yours is an obd0 if i'm not mistaken. are you putting in the d16z6? if you are you just need to get the obd0-obd1 harness conversion to a p28 ecu 90% sure. then just wire the vtec solunoid(sp?) straight to the ecu harness. i'm used to doin it in a obd1 car so its alil different then this but not much. just conect your stock harness plugs to the motor. there are a few thing more but this will give you an idea

u want to put in the si engine like the d16a6 (88-91 si? ) well eather way weather u r talkin about that or the 92-95 si/ex (d16z6) eather way go to www.rywire.com and go from there as far as your harness goes everything else u just hook up as if u were switchin engines i think~marcus
