Question:
Can you tell me it this product draws enough current load for my 2020 GMC Sierra 3500HD will recognize it as a trailer? I understand that the brake controller function may not work properly. 7 Way Trailer Connector Vehicle Tester C73NR Thanks

Expert Reply:
The 7 Way Trailer Connector Vehicle Tester # C73NR may pull enough power on your 2020 GMC Sierra 3500 so that your truck reads it as a trailer being connected so you can test the functions of your 7-Way. But some of the newer trucks have "upgraded" electrical systems (for lack of a better term) so you will likely need more of a power draw which you can get by using the Lamp-Out Sensor # 20142 which places a larger draw on your 7-Way.
