The number of electric signals available depends on the type of connector mounted on the inlet plate and on the number of signals used in the manifold: 37 pole Inlet connector : N. of outputs= 32 – used signals (max 22) 25 pole Inlet connector : N. of outputs= 22 – used signals Here are some examples of possible configurations and the corresponding pin layout both on the inlet and end plate :
