    3 wire to 1 wire o2 conversion

    What kind of resistor do I need to replace the heater with?

    why not just buy a heated o2?

    that reminds me i have a brand new 1 wire lying around

            not sure if it applys to the 3 wire also, but looking up my 4 wire i got---->

            Heater Resistance @ 68°F (20°C) Approx. 6 ohms

            so id figure as it heats up it would raise the resistance, which in turn lets me think anything @ /above a 6 ohm resistor should work, you can find some at radioshack in the bins....

              Sweet. Thanks for that info.

              The fourth wire is a ground, right?

                power and ground for the heater, and then reference and ground for the ecu. just find maybe a 10-20 ohm resistor with a higher wattage value, as the heaters constantly run and itll get hot and fail faster with a 1/4 watt over a 10 watt..... try somthing like this maybe....

                  Sorry, you lost me with that. There is still so much I don't know about electricity.
