I have a blank binnacle switch under the fuel tank flap switch. The blank switch is hooked up with wiring. Does anyone know where the wiring goes to?

Thanks in advance!

 

Typically the PDC (Park Distance Control - rear parking sensors) switch would be mounted there. That switch would allow you to turn off those sensors on occasions such as reversing a trailer. I'm guessing that is what that wiring loom is for. I would connect to nothing (it might be an interrupt switch?), or maybe the ECU.
