Does anyone know the order of the wires from the magnetic head to the circuit board? Does anyone have a picture?

There are two different board patterns, the early version where the wires where soldered in, the later version where they where in small sockets.
Beware of older units with the wires exiting the head that are covered by a blob of RTV. Too much stress and or flexing and the wires can break off at the head.
