help with wires

I have been checking around my engine bay and come across 2 unconnected wire connections and dont know what they do and where the should go, any help appreciated. the first is a black plug in connector with a 2 wires leading to it one is red/blue the other brown, the other is a clear connector with what looks like a cream wire and a brown wire coming from it. I will try and add a couple of pics where I work out how to upload them. Thanks

These are the wires im posting about both located on near side of engine bay.

I belive this is for front fog lights not that they are fitted to your car and I don't think the other end of the wire is even connected to the fuse box so don't worry about it.



At a guess is there are a wire going to the water expantion tank and is there a sensor fitted to it? Early cars dont have this and not sure what year your car is?




 

Thanks for that I did wonder why things all seemed to work. I have piece of mind now! Cheers.

2nd plug is brake fluid level sensor, the coolant level sensor is on the engine loom

Thanks rubjonny I will check it during the daylight.
