WARNING
Service air is identified by blue markings on gladhand; emergency air is identified by red markings
on gladhand. Do not cross service/emergency air lines at gladhands. Make sure they are hooked up
correctly to meet brake air pressure requirements. Failure to follow this warning may result in
injury to personnel or damage to equipment.

Service gladhand (Figure 3, Item 4) and emergency gladhand (Figure 3, Item 1) couplings provide the connection
between the semitrailer brake system and the towing vehicle air supply system.

is for 24V.
