It sounds to me like you have a bad ground so the circuit on your Pilot brake controller isn't able to read that a trailer is connected until you complete the ground with your circuit tester alligator clip like what we see with part # PTW2993.
Double check that your ground is securely connected to a clean, bare metal surface and that should fix the issue!
