Critical Function: The trailer wiring tester uses three LED indicators (Tail, Left Turn, and Right Turn) to visually show circuit power status. It can help you confirm whether the wiring of your trailer is correctly connected, ensuring that the circuit system is working properly
Reliable Quality: Made of high-quality ABS, the shell of the wiring tester has excellent structural hardness and can resist impacts without breakage or deformation. The metal contacts are highly conductive and corrosion-resistant, providing reliable connections and high current transmission rates
Simple Operation: The connector is plug-and-play. First, insert the connector into the corresponding interface of your vehicle. Then, operate the brake light, left turn signal light, and right turn signal light in sequence and observe whether they light up normally to determine the wiring condition
Broad Application: The 4-pin trailer tester connector has a rated voltage of 12V and a rated current of 20A, making it suitable for most vehicles with 4-pin plug interfaces, such as trailers, RVs, trucks, and campers. Please ensure the compatibility of your vehicle before purchasing
