When connecting double-conduit braking system conduits, first connect the yellow conduit to

control valve to automatically apply brakes). Trailer's conduit connectors and the tractor's
connection sockets must be free from any contamination. Pneumatic system conduit
connectors are equipped with rubber seals which must not be damaged or soiled.
