Nathwarr.... is the alhambra horns easy to fit (do they sit straight into the old holes) or does it require work?

easy as in 1 plug and 1 bolt yes, although it is very tight in there and the mounting brackets for the horns will need bending

buy yourself some plasters for your skinned knuckles
 
i fitted mine by taking the grill bit out around the fog light and then taking a couple of screw out that hold the bottom tray bit of the bumper on so i could get my hand underneath

How did you get the grill out Aimez?

Also, hwo much wiring is onvolved to just replace the standard one? :)
