  1. Does anyone know what wire on the PCM is the o2 signal wire on a 2012 5.0 ? the only pin-out online i could find was so damn small i couldn't make it out ....

    thanks, Don
  2. Easy to test for. Back probe the wires, engine running. the one that is fluctuating between 0.1-1v is the signal.
