1. Signal of reversing light is used to start rear camera in usually. So we can't get the back vision at ordinary time.So I add a switch and a diode to make it possible.
diode type:1.5KE12A 1500W 12V
Signal wire from the reversing light and get through of the trunk.
The switch.
Front camera can be turned to face inside and record drvier and passenger.
