  • One o2 sensorfor both banks?

    I need to know which wires to splice to get one o2 sensor to read for both banks. Any help would be greatly appreciated.

          I am trying to replace the two oxygen sensors with a single one.

          And I know exactly what I am doing, I'm trying to **** up my car. I think thats fairly obvious. So please stop trying to explain how YOU think oxygen sensors work. I know how they work.

          I appreciate the concern, but there is no way that moving the oxygen sensors 4" downstream is going to seriously screw up my computer. Hell they moved nearly that much when I put headers on the car, and that didn't change anything.

            Alright, you seem pretty intent on not listening to any of us, and you are being stubborn to the fact that this car ain't going to run right with a misplaced HO2S, let alone rigging the system up to only read for one sensor instead of the two it should be reading. So, I am going to tell you what you have to do to have ONE sensor. Do it exactly how I say, or you are really going to f*** things up...

            1. Find which connector you are going to use, then strip the outside insulation of BOTH HO2S connecting harnasses till you come to the four wires per harnass.

            2. Out of the four wires per harnass, two will match the opposite harnass to one another, that is the black (ground) wire, and the pink (power, or hot) wire. The other two wires are different between banks. For Bank 1, which is the left manifold, one wire is purple/white, for the Lft mani HO2S Hi signal input , the other is the tan/white, which is the Lft mani HO2S Lo signal input. On Bank 2, one is solid purple, which is the Rt mani HO2S Hi signal input, the other is solid tan, which is the Rt mani HO2S Lo signal input.

            3. Solder or connect the two pink (power, or hot) wires. Then solder or connect the purple/white wire of Bank 1 to the solid purple wire of Bank 2. Then solder or connect the tan/white wire of Bank 1 to the solid tan wire of Bank 2. You need not solder together the black (ground) wires, because they are already connected in one place and have one common ground.

            It should be like this when you are done...

            Pink + pink = Power, or hot.

            Purple + purple/white = Rt and Lft mani HO2S Hi signal input

            Tan + tan/while = Rt and lft mani HO2S Lo signal input

            Black + black = ground

            In all theory, this should work, but I am not guaranteeing anything. The PCM on this car will now be receiving the EXACT same signal to both the right and left manifold inputs, instead of a possible varying input signal between the two mani's like it was designed to do. If you have any questions or problems, post em. I expect to see something going wrong with this.
