The type of brakes your truck has won't matter so long as the circuit that activates the truck's brake wire signal has voltage on it when you press the brakes.

While there isn't a custom fit trailer hitch for your 2008 International 4400 ambulance, there may be an option for you with a weld-on hitch. It just depends on the width of your frame, and one with the correct drop.
