ok it took ne 4 hours (yes 4!) because their are two tricks no one tells you (if you know its like 15 minutes!)

fistly remove the alarm relay if present

1. DONT lay the seat back and lie upside down in the well on the seat..looks good, feels like it ought to work but you will never do it the access angle is wrong! You di it kneeling thru the drivers door (seat fully back!)

2. the bloody relay is secured by TWO securing lugs, one on eitehr side, simpley push a flat bladed screwdrivceer up eitherside of the realy and wiggel till you feel the catches open then sort of gently lever towards the steering wheel and the relay pops out...

its great though once fitted my test drive was in light rain and im already impressed....
