Descriptions
Part of towing responsibly is making sure your trailer lights are working properly. Whether you have just installed a new vehicle-to-trailer wiring harness or are trying to locate the cause of an electrical problem, 7-Way & 4 Pin tester is great for testing tail lights, turn signals, brake lights, ground connections and other electrical components on your trailer.
Directly plugging it into a connector socket on vehicle, it'll respond to the various electrical signals when you push the brake pedal, signals a turn, turn on the running lights, etc. When the socket is getting proper power, the tester's LEDs will light up corresponding to each wire in the connector. Testing your vehicle-side socket is essential after installing a new custom vehicle-to-trailer wiring harness and is highly recommended every time you hitch up to tow.
Also, if you are experiencing electrical problems with your trailer, tester will be able to tell you whether the problem is rooted in your vehicle's electrical system or if your trailer needs some rewiring.
