You also need to change your door modules that have the motor on for the window,the small plug/connection needs to have 11-13 pins in the drivers door and a few more in the passenger door depending on what functions you want eg reverse dip, puddle lights. Your door modules prob have 7 pins on them. Its so hard to find these used on ebay as theres so many, most of them useless. If you get lucky your probable looking around £300ish for both mirrors and modules.
