The speedometer signal is routing through the cruise control. Here are the wiring diagrams so you can see how the system works and the cruise control module so you can check it out. If the connections are good, I would replace the cruise control module, the signal must be getting lost internally. Please check the images below and get back to me, I am interested to see what you find.
