Carefully inspect the shorter of the speedo/cruise cables ( shorter is the
cruise)as the cruise cable can melt and jamb or twist up which can cause
damage to the governor as per Manny. The cruise cable is especially prone
with headers. Manny recommended not using the stock cruise set up once his
new Manny switch was installed.
