In a 2010 Subaru Forester, this particular wire prompts a linked machine, akin 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.
Realizing the proper wire’s coloration is essential for profitable aftermarket installations. Tapping into the fallacious 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 techniques, aftermarket options had been typically carried out utilizing this methodology.
