Bosch 15122 and 15511 O2 4-wire sensors $20
 

I just bought them, I am going to switch connectors from old sensors (cut and splice). They work only for 4-wire sensors. 5 and 6-wire sensors are wide band, they are different.
Original sensors are Denso sensors, they have different wire colors. So I need to know which wire goes where. There is a table of wire colors.
