Expert Reply:
With the brake pedal depressed the Primus IQ part # TK90160 should be showing you a display of how much amperage or power it is putting on the brake circuit. Your setup seems to be having an issue on the red wire of the controller. This needs to be connected to a circuit that shows 12 volts when the brakes are applied.
Typically a weak connection here will cause an issue or the other thing we see a lot is a blown third brake light fuse.
