Adam,
The boost/vacuum gauge should really be installed into a manifold vacuum port
on the manifold. If you remove the IAT sensor (relocate it), you have a
perfect hole for the boost/vacuum gauge. It will read boost, but make sure
that it's below the throttle body for an accurate reading.
On the A/F gauge wire, yes...you can tap into the PCM harness for the upstream
O2 but really shold have a seperate O2 sensor for the gauge (accuracy of the
gauge and won't affect the signal to-and-from the O2 to the PCM).
