The reason it's not connected is because this is a 1998 PCM swap into an older car. The 98+ evap system is different than the older stuff and incompatible so when I rewired the PCM connectors I left all the evap wires out.

I can give those pins 12v through current limiting resistors to simulate the solenoids being present and trick the computer.

...but I should be able to turn off these codes with software and I'd like to solve it that way if I can.
