o2 sensors

  1. Factory Five Roadsters
    I am using a 2001 Mustang Cobra SVT donor for my Mk IV build. I'm using the Mustang wiring harnesses and will keep what I must for the emission controls. Do I need to include both the front O2 sensors and rear cat O2 sensors (obviously including the catalytic converters as well)?

    I seem to remember a post that showed the pinout of the HEGO Y cable (was it dv/dt?) I junk yarded a Y cable and will cut it to extend the wiring to my HEGOs. But, of course, there are a couple of extra wires (oil sensor maybe) at the converged end. I know what the pinout is for the HEGO...
