In a 2010 Subaru Forester, this particular wire prompts a related gadget, resembling 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 the wire upon participating reverse gear.
Figuring out the right wire’s colour is essential for profitable aftermarket installations. Tapping into the improper wire can result in malfunctioning tools 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 programs, aftermarket options have been typically carried out utilizing this technique.
