I know it is old thread but maybe somebody are interested.
Only light are not working. No wires !
To do something you need rear lock boot to change with one with electrical connection and make some changes in the car.
From factory bulb and lock are connected to MAIN BODY ECU.
I bought from ebay some parts. :
original boot light, original lock, original electric button, door actuator ( with switch - off-on-off ). Some wires installed from front to back of the car. A little brain and it work.
If somebody want wiring diagram ( Toyota Aygo - -there are the same ) I can post it.
