Oyviny USCAR to RV 7 Way Trailer Plug Adapter + 7 Way Blade & 5/4 Pin Trailer Light Circuit Tester

The Silverado trailer plug is constructed using heavy-duty plastic, ensuring a reliable connection and extended service life. Additionally, the Nickel Plated Brass Terminal provides enhanced conductivity for optimal performance.

This GM 7 Way Trailer Plug is an ideal replacement for damaged or missing 7-pin OEM connectors, offering a standard RV blade 7-pin trailer wiring connector for easy trailer towing.

Featuring a twist-lock design, the GM 7 pin trailer connector can be easily mounted on the existing socket hole on trucks, allowing it to be twisted onto the hitch just like the original. No additional bracket or hardware is required for installation.

Offering a 3-in-1 design, this trailer light tester combines both a 5-way circuit tester and a 7-way trailer light tester, allowing you to test 4-pin flat, 5-pin flat, and 7-blade connectors. This versatile tool makes it easy and quick to test trailer circuits on most trucks. The upgraded double-sided design allows you to read the LEDs from both the top and bottom sides, further enhancing the convenience and accessibility of the tester.

Additionally, this 7-way RV trailer tester can be used as a 7-way to 5-way trailer adapter, converting the vehicle-side 7-pin output to a 5-pin flat adapter, enabling connection to 5-way or 4-way trailer light plugs.

The trailer light tester is equipped with bright LED indicators, providing a visual indication for each electrical function. By plugging in the tester and checking the green LEDs, you can easily identify any wiring problems, making the diagnostic process straightforward and efficient.
