speedometer & doorlocks & overhead mileage display quit working

Damn, I was looking through my service manual, and that's a very odd combination of things to fail. What were the events leading up to this failure? Speed is sensed at the diff, door locks on their own circuit, and the overhead is a BUS communication system to the PCM, i believe. I'll keep looking, in the mean time checking ALL fuses, circuit breakers, and relays would be an excellent idea. Even switching them around with others.

Hey, The overhead console not working is a fuse, IOD or something like that, in the cab, in between the drivers door and dash ( where they mate up )
The door locks would be a setting in the PCM, have to have the dealer do it, and they'll prolly charge you if you don't take it to the dealer often.
And speedo... not sure.. maybe it's got a VSS issue'

Broken wire to the speed sensor, or the speed sensor it's self:
"Vehicle speed and distance covered are measured by
the Rear Wheel Speed Sensor. The sensor is mounted
to the rear axle. A signal is sent from this sensor to the
Controller Antilock Brake (CAB) computer. A signal is
then sent from the CAB to the Powertrain Control
Module (PCM) to determine vehicle speed and distance
covered."
According to my manual, the speed sensor runs into the PCM at pins 25 and 28 on the C2 connector. I would assume that it is the middle of the 3 connectors. Check for continuity between the plug for the sensor, and the plug at the PCM.
