Hi All, I am in the process of switching my speedo from the instrument
cluster that I had with a clock in it to one that I bought that has a tach
in it.  I need to swap the speedo as I have a syncro and the cluster I
bought is from a 2wd so the speedos are not interchangable.

I noticed that the mt speedo has a circuit board and the appropriate plug in
the foil cable while the speedo that I am replacing does not have the board
hance the foil does not have the plug.  What does the board do?

I went ahead and plugged everything in and most things work just fine.  The
tach came to life without needing any wiring  - YEA!  It does popup on start
and then appears to behave fine.  The guages work fine except that the
blinking LED does not stop blinking.  The other thing I've noticed is no OXY
light and the high beam indicator does not work.  Can all of this be related
to the board?  Any ideas or suggestions?

Thanks!
Hans
