Trailer electrical interface converts from 24 volt Military standard (MS75021-1) connector or 24 volt 7 Pin SAE 560 to 12 volt civilian standard JAE 560 (7 socket). This allows towing a civilian trailer with a Military vehicle. The converter is normally mounted on the truck. The built in 12 foot coiled cable plugs into the trailer.
This model features a special ABS (Anti-Lock Brake System) option which creates the ABS signal for the trailer's controller from the vehicles brake light circuit. This model is required when the vehicle does not have a brake signal on circuit "M" of the vehicles trailer receptacle. Most M-series vehicles such as the M35A2, M275A2, M931, M932, M818, etc require this model when trailer ABS is used.
Converter is made in USA. We are an authorized factory distributor and the product includes a 2 year manufacture's warranty.

This model's ABS option only provides the correct signal to the trailer's ABS controller. It does not add ABS to a trailer that is not so equipped.
Aux input power is required for the ABS signal function to operate. Semi-tractor versions have this option factory installed. All other vehicles will need to add a fused (8 amp) power feed to terminal K on the vehicle's trailer receptacle.
