Anyone can help to connect dual Bosch Donut knock sensor to my 13B fd3s series 7 engine? I would like to have the pinout connection for the sig - and sig + of the sensors separately for each rotor to the link G4+ series 7 factory connector or inputs connector.

Thank you

Mike

There is only a single knock pin available on that ecu, pin 3O.  You will only be able to run 1 knock sensor, connect one side to the factory knock sensor wire, the other side to ground, the factory sensor used chassis ground so that will likely be fine for the bosch too.

So not use LINK AUX loom sensor groung wire?
