Sounds like you did a vtec head swap, use a p28 with odo-0 to obd-1conversion harness for ecu, same as dizzy, the new ecu harness will have the four wire 02, as for the knock sensor you can either drill a hole, tap it and insert the knock sensor in the back of the block were it would usually go, which i dont recommend, or get an s300, or you can downgrade but i love my s300, and turn off knock sensor. If you dont do this vtec will not kick in.
