The Hayes Air Utility Brake Control, part # HA100400C will work on your International tractor with air brakes towing your trailer with electric brakes. If the trailer has an electric over hydraulic system this control will operate the electric over hydraulic unit. On the Air Utility Brake Control, in addition to connecting to the air brake system, there are also 3 wires that will need to be connected.
The blue wire will go to the rear of your tractor and attach to brake controller circuit of your vehicles trailer connector. The black wire will need to attach to a 12 volt power source. The red wire will need to be attached to the output side of the tractors stop light switch.
You would also need to contact the International dealer or air brake system manufacturer to get the proper the 3-way tees, tubing, and double check valves needed for the air brake system on your International tractor.
If you do not have a connector present at the rear of your tractor that has an electric brake circuit you will need to check out the link below on how to install a brake controller from scratch. The link details everything you would need to purchase and how to install everything.
Another option for you and easier to install would be to get a Tekonsha Prodigy P2 Brake Controller, part # 90885, if you can find a dedicated stop light switch. This brake controller can sense when you are applying the brakes using internal accelerometers and will apply exactly the amount of braking power that is needed in any given situation, even in reverse.
I am including a link to the installation instructions on the Prodigy brake controller.
