In a 2010 Subaru Forester, this particular wire prompts a linked system, reminiscent of a backup digital camera 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 colour is essential for profitable aftermarket installations. Tapping into the flawed wire can result in malfunctioning tools or injury 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 methods, aftermarket options had been typically carried out utilizing this technique.
