This one interests me. Johnny bar should be tied in somehow to the rear service brake port of tractors that have them? ie, if I want to add one to my 925a2, how to do it? I'm guessing just compare the air diagram of a 931 vs 925, and replicate....I don't think the Johnson lever has any affect on rear line connections, just the 5th wheel trailer connections.
