Can anyone tell what this black/white & brown/white pair of wires is for and where it should plug into ? 2017 f type SVR.

 

If i'm not mistaken that wire doesn't plug into anything. I believe many people have that same wire just hanging. Could be for an option your car isn't equipped with, or more likely it is for advanced diagnostics or for software updates.

 

I am pretty sure it is for the battery isolation switch that is fitted at the factory for transportation. It is removed prior to the customer taking delivery.

 

Thanks all. I assumed it was for VelocityAPs upcoming flux capacitor.

 

If it ends in a small (usually white) plug then it's what JgaXkr said, it's used once and once only by the dealership to set the car up during pre-delivery.

 

+1. Just ignore it.
