The connector is missing on the engine side of the air bypass solenoid valve. I found the valve in the wiring diagram but I can't tell if the wires need to be connected in a specific order or if they can be switched. Any ideas?

 

If there is only two wires it does not matter how they are connected. The BAC is just a coil and needs to see+ and -. one of the wires should have +12v when the ignition switch is in the run position the other wire is - supplied by the ecu.

 

the air bypass solenoid valve is for the accelerated warmup system. why would you want that hooked up? It is not the same as the BAC valve.
