Sounds like you are looking for a wire to connect the red wire of an electric brake controller to on your 2003 International 8600. This circuit can be sometimes difficult to find but most commonly it is found at the brake pedal switch. Use a circuit tester like part # PTW2993 to test all of the wires going into the switch and use the one that only has voltage when the brakes are applied.

Another place is to find it is to use a third brake light circuit.
