different knock sensor on 1az fe, I'm changing dead engine with second hand one. my 2002 one has mechanical throttle, new engine electrical, decided to keep old one and finish the job asap. connected pretty all wiring plugs except water temperature one needed to shave one side and old knock sensor comes with one pin while new one comes with two pins. didn't take newer sensor of, but it looks that its attached differently as its held by bolt, while old one got tread and screws in to the block. any ideas how to deal with this?
