Electrical issue

[Ken 72]

I am trying to read my electric diagram for my 72 mach1 specifically the circuit # 16 which is a red wire with light green strip which is 16 R-LG My question is, there is another 16 R-LG but... it reads 16B R-LG What does the B stand for? other circuits have A B C D after the # what do they stand for I hope this is not a dumb question
