That would be ideal. Undo your wiring job, and make sure nothing is shorting. Mine had a tiny slit in the hot wire, which shorted out on the shielding. The best way to test is to check continuity from the ecu to the end of the wiring harness. If it ohms out, you know the issue isn't there. Here's the circuit diagram for you run into any issues between the ecu and knock sensor. [ http://home.comcast.net/~tanstrack/300ZX/KnockSensorSchematic2.jpg ]
