Can someone verify my understanding of the wiring on the O2 sensor plug.
Pin 1 - O2 Heat - 12Volt +
Pin 2 - Ground - 12Volt -
Pin 3 - O2 Return (Upstream or Downstream) - ?
Pin 4 - O2 Signal - ?
My questions are on Pin 3 & 4.
Generally, 1 of these is a 0-1 volt output from the sensor since these are narrowband. Then the other is either a 12Volt or Ground for the sensor signal input.
I'm wanting to prewire a harness to plug into the OE plug to deliver the O2 narrow band output from a Wideband controller.
Thanks for any help.
