• A = VC (1)
• B = input (1)
• C = start (1)
• D = sustain (1)
• E = output (1)
• F = pulse out + (1)
• G = pulse out - (1)
• H = VC (2)
• I = input (2)
• J = start (2)
• K = sustain (2)
• L = output (2)
• N = pulse out + (2)
• M = pulse out - (2)
• U = not used (0v)
• W = 0v
• X = +12v
• Y = +6v
• Z = -12v

Please note that the F and G, and N and M outputs may be swapped (e.g. G to F). My original panel has the original labeling crossed out, and the locations swapped, but due to other wiring errors I cannot be certain if this was a constructor error, or a panel marking error.
