I'm getting a DTC for the knock sensor, but don't know where it is. Is it on the block under the intake manifold, or is it on the head itself? Thanks for anyone that can answer this.

There's one on each side of your head. They are called ears.

Should be on the backside of the head itself.

I think it's on the back of the block. The knock sensor circuit (red/blue), which isn't there on the stock F22, is added at the same break out as the oil pressure sending wire by using the pigtail from the Prelude harness. This wire connects to the subharness and then to ECU pin D3.
