i didn`t have a fitting kit with mine either it should be alot clearer when you take the bumper off as how to fit it.

once the bumper is off take the fan off should be three screws i think,
undo the boost pipes connected to the old intercooler
and undo the bolts holding the intercooler to the rad
this does mean that one end of the rad wont have any fixing, but there is a hole on the end cap of the rad which i just ty wraped to the front panel then i sat the intercooler in the correct place (i also had a small ty wrap on the bottom of the intercooler holding it to the rad) and refixed the fan over to the left had side of the rad the same way that ford fixed it originally with the clips moved across, bumper and pipes back on job done

if theres a better way of doing this im sure someone will let you no
