In a 2010 Subaru Forester, this particular wire prompts a related gadget, corresponding to 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 means of the wire upon partaking reverse gear.
Understanding the proper wire’s coloration is essential for profitable aftermarket installations. Tapping into the improper 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 had been typically applied utilizing this technique.
