Hello everybody

Im new to the site so I apologise for my first post being for advice!

ive just bought a 2005 a3 tdi s line 2.0 and i have notice that two connector on either side of the radiator arent connected! I cant for the life of me find where they connect. I have taken photos of both of them so if anybody can offer some advice it would be appreciated so much!

this image is from the left side of the car as you look at it from the front


this image is lower down and from the right side as you look at it from the front




 
Yellow one is crash sensor on front panel, and then other looks like it could be for horn or outdoor temperature sensor
 
Look at the last pic there is also a brown bare cable? What is that for? Has it had a front end crash?
