Review on 🔧 APDTY 028252 Engine Knock Sensor with Harness: Enhance Engine Performance and Safety by Carl Henderson

I checked the knock sensors myself with an oscilloscope, they work but the wiring harness they sell is advertised as suitable for the Nissan 300zx. It definitely does NOT match the plug. I have an aftermarket ECU and access to tools to make my own connectors so I can get by. However, I'm sure this is unacceptable to most people, which is why I'm giving it 1 star for false advertising. I was also disappointed that the manufacturer only chose one side of the connector (one of the two). the sensor pins are connected to the ECU) - although the sensor itself is grounded to the chassis (so that works), it produces a louder signal than if the sensor were grounded directly.
