Sonac Posted June 18, 2021 Report Share Posted June 18, 2021 Just purchased a Link Knock sensor with loom. I have the plug and play G4x, looked at the pinout and it seems the stock knock sensor is hooked to pin 42. Its a one wire sensor. As I understand it, I run the new loom to the ECU and hook the white wire to pin 42. What should I connect the black wire to? Not sure which ground to use. Thanks Quote Link to comment Share on other sites More sharing options...
