Youll need to either wire up OBD1, or get a preOBD to OBD1 conversion harness to run the P28...

The PR3 is for a B16 preOBD engine, and will look for things your engine dosnt have, such as the knock sensor, secondary O2 sensor,ect... So the PR3 wont work without modification... The P28 is the best way to run that head on that block...
