In a 2010 Subaru Forester, this particular wire prompts a related machine, comparable to a backup digicam or parking sensor system, when the car is shifted into reverse. This activation is achieved by sending a 12-volt sign by way of the wire upon participating reverse gear.
Understanding the right wire’s shade is essential for profitable aftermarket installations. Tapping into the incorrect wire can result in malfunctioning tools or harm to the car’s electrical system. This automated activation enhances security and driver consciousness throughout reversing maneuvers. Earlier than the prevalence of built-in infotainment programs, aftermarket options have been typically carried out utilizing this technique.
