Firstly designed for my Lifan Smily (Lifan 320) car

A rear wiper functionality expand device. Should be connected into a gap wires going from column switch. Functionality scenario:

1. Turn rear wiper on;
2. Turn it of after a bit of time;
3. Turn it on again. The wiper works with a defined delay.
