What are you trying to install?

Expert:  George H. replied 9 months ago.

Why do you want to bypass the connector, the O2 sensor needs to "breathe" through the sensor wire. Are you going to solder that solid?

What are you installing? I can help match the truck but I need to know the sensors you are putting in.

Thank you,

Connect the two white wires of the sensor to the dark green/orange and the black/white wires. Does not matter which is which.

The blue wire of the sensor goes to the black/light blue wire of the truck.

The signal wire of the sensor (black) goes to the tan/red wire. It cannot be sodered.

You may have a tan/white stripe wire to connect, it is the signal wire to the black wire of the sensor.

On the back sensor the signal is orange/black and the blue wire is connected to the black/light blue

Let me know if that is clear
