RZtwin Posted October 18, 2020 Share Posted October 18, 2020 (edited) Is this the proper way to wire new Bosch knock sensors? My jdm supra 2jzgte currently has 1 wire going to each oem knock sensor. Using Haltech elite 2500. 1. Does polarity matter??? 2. Do I NEED to ground shielding mesh to body ??

Mike2JZ Posted December 19, 2020 Share Posted December 19, 2020 2 Wires needed for Bosch knock sensor. 1 Wire to Knock Signal, other wire to sensor ground. Ground shield wire to chassis or power ground. Polarity does not matter. If you are running two knock sensors, you can have them share signal ground and shield ground. Knock signal must be independent. Quote Link to comment Share on other sites More sharing options...

Does my diagram look correct? Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted December 19, 2020 Share Posted December 19, 2020 I mean you could, but if you are having to run a shielded wire, then I don't see why you would use the OEM signal wire. Just use two core shielded wire and run it from the sensor down to the ECU. You must make sure that signal and ground wires are shielded otherwise you can get very bad electrical interference.
