Oyviny Multi-Tow Trailer Wiring Adapter + Tester

For long-lasting use, this 7-blade RV trailer tester is made from durable ABS plastic, which will never rust or corrode. Tin-plated copper terminals ensure great conductivity. The Multi-Plug Design of this dual-output trailer adapter allows it to simply replace the 7-Way USCAR connector that came with your vehicle, featuring both 4-Pin and 7-Pin connectors in case you have multiple trailers with different connectors, adding versatile towing options.

This USCAR 7-pin trailer plug adapter is USCAR Specific, designed for specific vehicles with a factory tow package, compatible with Ford, GM, and Dodge vehicles with the factory 7-way USCAR socket. Please note: Check the connector behind your vehicle before buying.

The 3-in-1 Design of this trailer light tester combines both a 5-way circuit tester and a 7-way trailer light tester, allowing you to test the 4-pin flat, 5-pin flat, and the 7-blade connectors. It's 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.

This 7-way RV trailer tester can also be used as a 7-way to 5-way trailer plug adapter, converting the vehicle-side 7-pin output to a 5-pin flat adapter to connect the 5-way or 4-way trailer light plug.

The Versatile trailer wiring tester can be used to test 6 separate trailer light functions, quickly confirming the functionality of taillights, brake lights, reverse lights, turn signals, electric trailer brakes, and 12V auxiliary power on your vehicle.
