wiring help: German VDO gauges

[POS carb]

anyone know how to wire these damn things? lol

I have a VDO Temp, Voltage, and Bar gauge from a VW, also another Temp gauge from an Audi.. They all look the same and have 3 connector pins on the back (except volts, only 2) , anyone know how to hook them up or where I can find the sender unit specifications?
:rice:

never mind I figured it out... But I can still use stats for the BAR gauge... I would like to hook it up as a boost gauge...

Temp
the 144+ goes to ignition +, the upside-down "T" goes to engine ground, the G goes to the temp sensor.

Volts
the 144 is voltage +, the G is engine ground.

Bar
need more info
