i'm going to fit sx dials. I believe i need a sx temperature sensor for this to work? Thats it? Ford anyone know where i can get hold of one for very cheap or a user sell (give) me one? Thanks

where are you based???? if you go to eurocarparts with the car reg they will give you the correct part (number 224650010)

I found this site a couple of days ago & orderd to my 75SX
(Its a 3-pin sensor, if u´r talkinga about the water temp..)
