Have a look at "TE ML 2" on this page: https://www.polevolt.co.uk/acatalog/Screened_Cables.html  This is the common M27500 that is used in motorsport, probably overkill in a road car but if you only need to buy a few meters it doesnt usually work out too bad.  150°C rated so a bit more suitable than the 70°C rated belden above.

What is the correct wiring if we use shielded cable? We bridge the shield's wire on ground wire that one goes knock's sensor signal - and at other side  also we bridge the shield's wire on knock's signal - which it will hook up on ECU's ground pin? I mean we don't individually ground the shield's wire somewhere to chassi or something?

At the ecu end of the cable, connect the shield and the ground wire to sensor ground.  At the sensor end of the cable dont connect the shield to anything.

Okay. What's thw difference if i ground the sensor's negative on chassi? ECU gets ground from chassi. It should be same correct?
