In a 2010 Subaru Forester, this particular wire prompts a linked machine, corresponding to a backup digicam or parking sensor system, when the automobile is shifted into reverse. This activation is achieved by sending a 12-volt sign by means of the wire upon participating reverse gear.
Figuring out the proper wire’s shade is essential for profitable aftermarket installations. Tapping into the flawed wire can result in malfunctioning tools or harm to the automobile’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 methodology.
