 in celcius; is it coolant temp or oil temp? And, how do I hook them up?
 Where does the wire to the voltmeter get attached and the temp gauge
 wire go to. If it is an oil temp gauge, I suppose it is not useful to
 me, or is it ? Thanks for the help.

fyi, you can still get the senders/lines for these from VDO.  i am installing
a '81-'83 audi 4000 3-gauge cluster in the same place, the plastic heater
cover in front of the shifter..it fits well, and looks stock.
