Well, then forward — do wiring.

Now you need to determine what light indication you choose. Perhaps you need a dimensional lights or turns to come to the robot with a dangerous signal. Well, then forward — do wiring. It must be laid from the central unit control unit. Starting from the scheme of your car, start installing it to all consumers. Before bringing the doors, you must definitely find out the polarity of your car. Most likely, if it is a foreign car, or less likely, if it is a domestic car, they have a negative polarity. And only when you are 100% convinced of polarity, you will need to combine the ends with the corresponding input of the control unit. Then there will come the turn of the ending on the trunk and hood, and then you need to draw wires again to the central block.
