Thanks again for the quick reply. I found one sensor wire connected to the Y6120 Charcoal filter valve aka Purge Valve that has a grey wire and a grey and brown wire, which I must assume should be connected to the X6205 Intake Air Temperature Sensor if I am reading the wiring color code abbreviations correctly GR & GR/BR (I am guessing it means Grey and Grey with Brown stripe) . The schematic for the Y6120 Charcoal Filter aka Purge Valve shows a RT/WS and BR.

Any idea what RT means? I also have a harness connected to the Evap Systems Purge Control Valve, which I can't find a schematic for, but that sensor connector has a brown wire, and a Blue with a red or orange stripe.

Thanks again for your time and help!
