typ44T spazzy speedos (5kT, and 200T)

update:
my speedo on my '86 5kT was intermittant,and i was told to remove it and 
check for a loose connection on the printed circuitboard.  i pulled the strg 
wheel, the combi switch, and pulled out the speedo cluster.  looked for 
breaks in the circuitboard. could not find any, not to mention that the 
diagram i printed out was from a '89-'91 turbo. it all looked greek to me. so 
i put it back in, and it has been working fine ~mostly~ up until now.  Now 
the speedo needle is going haywire again..   any more ideas? 

my friend just bought a '89 200Turbo. his speedo is worse than mine, it's 
completely dead, tho every now and then the needle will jump up a few times.  
Any tips i can give him on how to remove the speedo from a '89-'91? i know 
how to take one out of a '88 down (gotten quite the expert at that) but am 
clueless about the '89-'91 dash/speedo removal. 
Also what was the URL to the site on repairing the intermittant speedo 
problem? 

any help would be appreciated  -
