I still need to do this to mine.....
although I might wait until the wife gets fed up with using the key first (and then get her to pay someone to fit it
)
Get the plug and play loom the company sell for about £16 and it just plugs in the pump no cuting wires its a 15 second instal that way !
Only have to swap the lock / unlock wires over as the loom is wired wrong
