The ground for the shielding of the knock sensors goes to ground point "B" and is the intake manifold ground. It should be bolted to the underside of the intake. Kinda hard to see with the motor in the car, but you can see it at the right angle with a flashlight.Correct me if I’m wrong it looks like the coax from the cable will be ran to the air flow ground to be tied in, I will look for that when I get home,
I’m an electrician for the movie industry so wiring isn’t that complicated to me but when I see people on YouTube do it differently and rear three write ups that all did it differently it’s really confuses you lol
I appreciate you guys so much!!
If you scroll back a couple pages in the EWD you can see what else ties into that ground. I think it's mostly sensor grounds. It was working a minute ago, but now isn't loading for me.

To be clear, the ground for the knock sensor is the sensor body itself. The ground for the shield is just to keep the shield nice and clean so the signal doesn't get any significant EMI.
