Greetings All,

I recently installed a VDO Boost/Vacuum gauge in my 1999 Audi A4 1.8T.
It works fine, but I have been holding off on wiring it into the
instrument cluster's power supply because I am unsure of where or how I
should tie it in.

Does anybody have a wiring diagram or some words of wisdom they can
pass along to provide me with some insight on how to locate both a
power an ground supply? My goal is to light (and dim) this gauge with
the other instruments. This is a "new to me" car so I do not have the
Bentley yet and hate to start probing around without some direction.

Thanks in advance,
-Jeremy

 

May want to search history here and on Audiworld.com

IIRC you connect to the 75+ terminal in the fuse panel on drivers end of the dash.
