15 days after it was installed.
I knew nothing about installing these but this type was very easy. Sure there was that extra orange wire but that was not needed. It took ten minutes max to hook up. Five minutes to learn how to work it and that was that. The instructions are better than usual. The little stickers they use to label the wires may fall off so use clear tape to fix them on or be very careful with them. Have 2 AA batteries that it will need to work. Easy to install and easy to use. I was expecting it to be harder or more complex, I was pleasantly surprised.
