A connector tester works by plugging into the connector socket on your vehicle and responding to the various electrical signals produced by pushing the brake pedal, signaling a turn, turning on the running lights and so on. When the socket is getting proper power, the tester's various 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, This 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.

  • Confirms proper function of vehicle-side wiring connector
  • Tests 7-way for tail, brake, reverse, turn signals, brakes and auxiliary power
  • Features a label for each LED, indicating the intended function
  • Constructed with LED lights for long-lasting use
