Welcome. The KS is located just above the starter and next to the oil filter. The OPSU (oil pressure sending unit) is also in that area. The KS is short and wide (~1.5"), whereas the OPSU is slimmer and depending on the gauge config, can either be short or long.

Well, a knock sensor has something to do with the ignition, basically to adjust (retard) the timing if it detects detonation in the engine.
