just install a speedo cluster from a '85-'91 with the tach and digital
clock already in it...  you can find them used..

Why  would VW start installing tachometer's in '85 full campers, but not
the
Wolfsburg weekenders??  I'm lucky enough to have an '85 weekender  with no
tach, so I'd like to install an aftermarket tach.  Picked one  up at my
FLAPS
for $30. Wiring seems straightforward, but I've got a few  questions.

First off - do I need to run a wire all the way back to the  coil, or is
there a wire already from the coil to somewhere in the dash? (I  only ask
because I know some '85s came with a tach from the factory, so  maybe that
wire is part of a wiring harness?).

Next question - I'm  trying to figure out where to mount this thing so that
it looks the  cleanest, and is in good view.  My first thought was on the
dash, to  the left of the instrument cluster right in front of the side
window dash  vent.  Unfortunately, the mounting hardware that came with the
tach  won't allow me to tilt the guage up to compensate for the downward
slope of  the dash, so I'll have to fabricate something. Then I got to
looking at the  instrument cluster and noticed the space, dead center, that
is directly  below the idiot lights is about the size of my tach. I've never
seen any  lights come on in that space - it looks to be a cheesy 'fake'
notification  center or something. Has anyone here ever installed a tach (or
any other  gauge) in that space? Any reason not to? (assuming I have enough
clearance  behind to fit the depth of the guage, probably 2"). Click link
