Electric Trailer Brake Controller For a 2018 International LT 625 With Air Brakes


Id like to add an electric brake controller to a 2018 International LT 625 with air brakes. Any advice?


Expert Reply:

You are going to want to use the Hayes Air Actuated Trailer Brake Controller # HA100400C on your 2018 International LT625. With this brake controller it will tie into your existing air lines for your brakes and use the pressure in the air lines to proportionally match the braking force applied to the electric trailer brakes.

The only connections you will need to make are for the Air Line # RM450700, and electrical connections. The white wire from the Hayes controller will go to a 12 volt ground, the black wire to a 30 Amp Circuit Breaker # PK54530 connected to a 12 volt positive source and the blue wire to your trailer connector for the electric brakes. The red wire is not required as the air line will provide the input to the controller to tell the trailer when it needs to brake.

I have linked the instructions below that you can reference for additional information.
