Michael--

I have a tach and later model cluster in my 83.5 Westy. When installing the
newer cluster (say from an 88 Vanagon) I swapped the blue flexible curcuit
board. It's been several years, so I don't remember exactly why. But what comes
to mind is I had some trouble with the oil pressure light/buzzer. I think the
 problem was the oil pressure light didn't work at all on my set up. but
again I  don't exactly remember.

I got the blue flexible circuit board from, I think an 85  Vanagon, maybe an
84, with a tach and attached to the "newer" tach and  cluster pod.

I also used my original speedo from the 83. And now that I think of it that
83 speedo kept any current from getting to the oil pressure idiot light if I
used any curicut board from a 2.0 L vanagon. The 83 speedo does not have a
buzzer system at all.

So the way the later model (2.0L) curcuit board was routing the current, it
wanted to access the L shaped circuit board with the buzzer in the speedo
first,  then send power to the idoit light through the L shaped board. But with no
L  shaped circuit board in the speedo the current just ender there and no
power got  to the light.

So again I got the blue flexible curcuit board from an 84 or  85, which both
had the 1.9L and I believe had the tachometer as an option. So  there was the
"optional" curcuit board available which was wired to give the  tach power and
get power to the oil pressure light as well. This board had  no provisions
for the buzzer because at that time it wasn't installed on the  Vanagon.

I hope that made some sense.

Best,

Yes it  is still a stock 1.9L. I still have the original cluster. Could i
swap the  circuit board? The 2.1L "2" switch setup, is this 2 senders? Can I
replace  my sender with the 2.1L sender?
