I don't have a repair manual for your Ford, but I will take a guess at your speedometer problem. It's lilkely the "distance sensor", a little dohickey that generates pulses whose frequency is directly related to the speed of the output shaft of the trasmission. This transducer is located on the transmission where the speedometer cable once was, in fact, on some transmissions, it is a direct replacement for the cable drive. Its easy to change. However, don't wreck the electrical connector. It should be a weather proof type.

Your other problem is more complicated. My first thought is a lost ground. This will require a circuit diagram and tracing the circuit until you find where the interruption is. Don't be surprised if you find a corroded stab-on connector in a multi-circuit contact block. (I had a Chevy once that lost the gas gauge signal. The problem was traced to the use of aluminum wire in that circuit. It must have been a cost saving attempt. One wire in a 8-wire flat cable was aluminum. Now, how much cost savings was that? The circuit was lost in a connector in the trunk were there was change from aluminum to copper wire.)

Look for places in the circuitry that is common to all the devices that conk out at the same time. Is this circuit powered up by a relay? If so, make sure this is working. You have already covered the fuses, but is a there a breaker-relay in the works somewhere? Hopefully, it is not a ground connection behind the dash. Those are stinkers to get to.

Hey Jemdandy,
O.k., will do...yeah, I think the 2nd problem is going to be alot harder to find. Thanks a bunch for your advice!
