In the throws of gauge woes

Follow The wires from your O2 sensor, the signal wire goes to a connector
mounted on the passenger side fire wall.  There is about four connectors
mounted in a column.  the o2 signal wire is the lowest or second to the
lowest connector.

As for the boost gauge plumbing, I ran the tubing down my a-pillar (both my
gauges are on my a-pillar), under the dash to a existing grommet, that has
multiple vacant places to pass a wire through the firewall. then I
installed a Tee to the back of the manifold to connect the other end.  I
can take a few pictures if you need to see it.

I have a suggestion,  put a switch on the Airfuel gauge, so you don't have
to see the blinking light show all the time.
