In a 2010 Subaru Forester, this particular wire prompts a related gadget, equivalent 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 the wire upon partaking reverse gear.
Realizing the right wire’s shade is essential for profitable aftermarket installations. Tapping into the mistaken wire can result in malfunctioning gear or injury 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 methods, aftermarket options had been usually applied utilizing this technique.
