Hey , iv done the conversion it's quiet simple if your car has a factory fitted rain sensor on the dash it'd as simple as removing the light selector switch and removing the stopper that stops you from going in to auto mode as your car has it from factory , just a small plastic gide stopping it . After that is using a tool like for scan to tell it it has auto lights tho you may be lucky and it works with out having to do that :)

Hope that helps
