it's hard! you have 2 knock sensor under you plastic intake. than you take your intake off you will see a wire with two black top about 1 1/2 to 2 in. pop those off and there there they are. it is a good idea to replace them both and get you a new wire from the dealer fro the knock sensor. i hate to hear you have to do it twice just cause you did not want to buy the knock sensor wire. and if you careful you can save the intake gasket. be sure and buy all you parts first. 2 knock sensors , knock sensor wire and intake gasket. if you don't used it take it back .
