Product description Key benefits Automatic camera activation: Builtin trigger wire lets your reversing camera power on automatically when the vehicle is shifted into reverse, eliminating manual switching. Secure, vibrationresistant connection: Female connector includes a locking screw to prevent accidental disconnection from road vibration or movement. Plugandplay compatibility: Standard 4pin aviationstyle maletofemale connector designed for common reversing camera systems that use a separate trigger line. What it does 4pin male to 4pin female aviation connector: Provides the standard plug format used by many reversing camera installations. Female connector with locking screw: Locks the connection in place for reliable, longterm use. Trigger wire on the cable end: Connect the trigger lead to the reversing light power supply; when the reverse light is powered, the trigger forces the camera to start automatically. Important attributes Function: Transfers the camera's power/video and includes a dedicated trigger lead to signal the monitor when to switch to the camera input. Compatibility: Fits systems that use 4pin aviationstyle connectors and a reversetrigger input. Ideal for most aftermarket reversing cameras and monitors that accept a 4pin aviation plug and a trigger line. Size/specification: 4pin configuration (male to female) with an integrated trigger conductor and female locking screw. Reliability: Designed to maintain a consistent electrical connection and prevent accidental unplugging via the locking screw. Typical use scenarios Installing an aftermarket reversing camera on a passenger car or SUV: Use the 4pin maletofemale aviation connector to link camera and monitor; connect the trigger line to the vehicle's reverse light circuit so the camera switches on automatically when reversing. Replacing a worn or damaged connector on an existing camera harness: Swap in this male/female aviation plug to restore a secure, locking connection and trigger function without rewiring the entire system. Fleet or commercial vehicle retrofits: Add or upgrade reversing cameras on delivery vans and service trucks to improve safety; the locking female connector helps prevent disconnects under heavy use. Installation notes Connect the 4pin male to the 4pin female aviation plug to complete video/power paths. Attach the trigger wire to the reversing light power supply (typically the +12V reverse circuit). When the reverse light is energized, the trigger will signal the monitor and the camera will start automatically. Ensure connectors are fully engaged and the female locking screw is tightened to secure the connection. This product preserves the original 4pin aviation maletofemale configuration, includes a locking screw on the female connector, and features a trigger line intended to be tied to the reversing light power supply so the camera can autostart in reverse gear.
