I will try and find time tomorrow to pull mine, clean the connections (they are oil soaked) and check it all out.
 
Had the same issue with my '93.

Replaced the pig tail for the VSS #2 on the xfer case output, purchased from cruiserparts. No difference.
Replaced the #2 VSS with used part from cruiserparts, no difference.
Had mechanic try to fix it while it was in his hands, he replaced VSS #2 with new unit, no difference.
Mechanic swapped in used gauge cluster, no difference.

Figure it is a short somewhere in the wiring somewhere, figure I will work on the wiring when the motor is out (burning oil will be swapped with LS or rebuilt).
 
I’m guessing my VSS should not loook like this? Looks like it’s missing the connector pin inside. At least I know why my speedometer and odometer aren’t working.

Inside the port on the side of the t case, that area has some built up gunk in it, what’s the best material to use to clean it out? Electronics cleaner?

Recently I had the pictured unit freeze and break the pin....make sure the unit turns freely before replacing the pin(still available from Toyota]
 
Just something inexpensive to check out. Check your grounds and your positive connection to your alternator. The nut that holds the positive to the alternator had rusted out and I had a very loose connection and was experiencing a periodically dead speedo. Tightened that connection and no more dead speedo.
 
My speedo had an intermittent fault. I recently discovered a harness connector for the speedo sensor harness that is on the topside of the t-case had disintegrated and was losing connection.
 
Did 80's in the US have the cable speedo (mechanical) or did they all get the electric speedor? My 3/92 80 has the mechanical version. I have a spare cable (new genuine oldstock) to fit one day as the speedo needle 'chatters' a bit at higher speeds. I would have no idea where to get replacement speedo heads, etc if I ever needed to. So far the odo still counts properly and it's not too far off the first digit becoming a '7' now.

93 & older had a mechanical, 94 & newer had an electrical
 
I am battling this now too. Wires look fine. What ground is this? Also, VSS appear normal?

Edit: I believe the pin is broken?
 
I may have a spare in my extra transfer case. Shoot me a PM and I'll check in the morning.

It won't fix the cause of the break, but if will get you going again if you fix the root cause.
 
Wonder what caused the break? I'm at 220k now and it was original. Thank you for offering a spare, I just ended up ordering a new VSS.
 
My speedo & odo do not work. No dummy lights or codes coming up. Read some threads and can't figure out where to start, already swapped the speedo sensor on the transmission. I thought I read that there is another part that goes with the sensor maybe I misunderstood. The wiring under the truck looks good, not sure where to look in the engine bay to check there. How hard is pulling the cluster? What else should I be checking? Also the truck has died a couple times while coming to a stop, starts right back up no issues, might they be related. The shop I use could not reproduce it or find anything. Thanks for all the input so far everyone my truck is coming along nicely except this stupid speedo issue.

Thanks,

Cory
Did you ever figure this out? My speedometer and odometer no longer work. The dash flashes OD off often. It dies sometimes and restarts immediately when switched to neutral and turn the key. I havent tried the cruise control in a long time but i do not believe it works.

Mine was the sub-assembly on the transmission. I didn't have any of those other issues.
