In a 2010 Subaru Forester, this particular wire prompts a linked system, comparable 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 way of the wire upon participating reverse gear.
Understanding the proper wire’s coloration is essential for profitable aftermarket installations. Tapping into the mistaken wire can result in malfunctioning gear 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 applied utilizing this methodology.
