In a 2010 Subaru Forester, this particular wire prompts a related machine, corresponding to a backup digital camera 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 partaking reverse gear.
Figuring out the right wire’s shade is essential for profitable aftermarket installations. Tapping into the improper wire can result in malfunctioning gear 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 had been typically carried out utilizing this methodology.
