Horn not working

Hello again.

I have recently replaced the steering wheel and airbag on my 300c because none of the buttons or horn worked. Now everything except the horn works.
When i got the car it has already had another horn wired up, as it would not pass the MOT without it. I have called the Chrysler main dealer to ask about which fuse or relay is for the horn, but as usual they were of no real help and suggested booking the car in so they could bum me. I have looked through the owners manual and none of the fusebox diagrams make any reference to a fuse for the horn.
I have taken a photo of the fusebox in the engine bay, can anyone tell me if its missing the horn relay or which fuse it is please?
Remember I am NOT responsible for the installation of the aftermarket horn!

If the fuse & relay are OK, check the spade connection to the horn to make sure the wire is not loose. If there is voltage at the horn when pressed, then the actually horn itself may be defective

One step for man, one giant leap for mankind

The problem is, I don't know which relay is the horn relay. It does not say in the owners manual.
Regards

Things I've learnt today.
The relay is the one on the top right of the picture and its working.
Fuse was not blown.
The horn button in the centre of the steering wheel needs to be pressed REALLY hard
Thanks for the help guys.
