Apparently that connector has the driver's seat +12V feed right next to the vref 'A' circuit, in my case the connector was soaking wet with condensation from...

  2. VRef Voltage 'A' out of range

    Alright, made some progress... Unplugged the ECU and the short went away, but there are 3 pins on the ECU that are vref 'A', 12 13 and 14. Only 12 and 13 are used, 12 is APP vref A, the harness side isn't shorted, but pin 13 is... Which according to the ECU pinout is for the fuel tank pressure...

I'm not entirely sure if the pedal itself is bad, I bench tested it and I get sweeping voltages on it on both circuits... But when checking vref...
