I just installed a vac/boost gauge in my 95.5 S6, tapping into green air li=
ne in the drivers footwell.  I must have missed the list-post that said "do=
n't do that".  I am happy to report that I get +5 psi whenever I use the do=
or locks, but other than that the gauge just sits there with nothing to do.=
  I think this gauge might be a lot more useful measuring intake manifold v=
acuum and pressure - where's the easiest place to tap in?  I know there's o=
ne for the ECU on the passenger side, anything closer?

For others who might choose to take my route check the lock pressure before=
 moving on to use it as a boost gauge - you'll want to add  a McMaster-Carr=
 5449K192 5mm tube coupling to your supply list...
