When trying to find your brake signal on your 2019 International 4300 I recommend starting at the brake pedal and looking above it for a switch operated by the pedal. Test those wires using circuit tester part # PTW2997. Basically press the brake pedal while testing the wires. The one that activates with the pedal pressed is the one you're after. If this is not present then the next best solution is to use the third brake light or standard brake light signal that can usually be found in the fuse panel.
