Well,
I spent sunday afternoon installing a VDO gauge set from a 1979 GTI into my
84 Westfalia.

I remember reading in the archives that someone was stating that the gauges
will not fit in the plastic bit under the radio.  Well, in my 84 Westfalia
there is room to spare and they fit quite well.  I installed a VDO Volt
Meter and a VDO temprature gauge.  The only problem is the viewing angle -
I can't read VOLT or TEMP at the top of the gauge - reading the gauge is no
problem though.

The Voltmeter is about as simple as it gets.  Ground (31), and Power with
key on (15), plus the dash light connection

The Temprature Gauge is a little more interesting.  There is a switch
installed next to my gas heater knob that allows me to select between the
cooland and the oil temprature.  Pretty neet - I only took it for a short
ride today but the setup seems to work quite well.  This week I am going to
get a three position switch and another sender and install the sender in
the radiator so I can monitor front and rear water temps.  Should be quite
interesting - especially this winter!

The third thing I did is run some RG-58 cable from the rear to the front.
This is attached to the Oxygen sensor so I can get a 0 to 1.00 Volt Meter
and monitor the mixture... so far today I just had my Digital multimeter on
there and I running lean on the highway - Yikes!

If anyone is interested in photos or has questions on the install - please
let me know.
