Speedometer not functioning - need help

Speedometer not functioning - need help
Electronics are not my forte. My speedometer has quit working. I have swapped the speed sensor with two other known good speedo sensors, and tested them all, and they all check out as working.
I'm looking at the FSM (page EL-78 for the 95 max) but reading electrical diagrams is not my thing. I need help. What are M58, M50, F105, F102, etc? What is the next step in troubleshooting this?

the ground for the speedo is shared by the fuel gauge, and the fuel gauge works fine, so it's good. it must just be a wiring discontinuity problem. time to start tracing those two wires. i realized after I posted this that the Ms and Fs are male and female connectors.

I tap my dash top to get it going again. It seems to rejuvenate above 40mph. So usually, I don't think about it till I get into 5th gear, then I start tapping the dash top if it hasn't already woken up.
I've replaced my sensors, did the continuity check, but nothing. I'm thinking it's the guage, but there's not much I can do besides replace it. If you could take it apart, you could easily roll back the odo, and I'm sure they wouldn't like it if you did that. Good luck and keep posting updates.

Nealoc187: how many miles you got?

Good that you got it figured out though.

yes. i put the front up on jack stands and started the car and put it in gear. unplugged the harness from the sensor and checked the voltage just to make sure the sensor was outputting the correct voltage, it was. then I checked the same wires behind my gauge cluster and there was no voltage, so I knew it had to just be a break in the circuit somewhere. I just ran two new wires to the speedo from the sensor and problem was solved.
