There seems to be a wiring problem with your Tekonsha Primus IQ Brake Controller part # TK90160. The first place I would look is the ground wire of the controller. You need to make sure it is connected to the negative post of your battery.

The next place I would look would be the power wire of the controller, it should run to a circuit breaker and then from there go to the positive side of your battery.

I attached an FAQ article on troubleshooting brake controllers for you to check out also.
