Hi Bob, I'm going to chime in on this one because my S.W. tach will not read the tach out put from my Crane HI6. I understand the the the tach output splice to orange 40 but the the drawing shows a second tach splice to the red msd wire. What is this wire so I can translate to the Crane and what does it splice to on the S.W. tach? Maybe I will need a tach adapter from Crane-same part#- but I'd like to try this first. Thanks for all your previos advice and help.
