ok i was doing work on my car and had to take the wires off of the knock sensor and the thermastat fan thing and the look the same but one wire conecter is white and one is black and i cant remember what one goes where can some one please help. thank you

 

the white wire connector should have a dark blue wire in it. that is the knock sensor. and the other should be a dark green and white wire which is the coolant sensor.
