Lay the gauge mount over the factory
pillar (or new factory pillar w/o
speaker hole) and mark locations (notice
X's) for the wires/tubing to pass
through. Mark your locations
low in the gauge hole so that the
wires/tubing do not have to bend
upward. Use a step drill and
drill your holes large enough to
allow the connectors to pass.
The step drill is recommended as it
will not crack the plastic.
Now is a good time to make sure that
your gauges will fit in the pod
holes in the mount. If they're
too tight simply use a piece of 220
grit sandpaper and gently remove
some material from the inside of the
holes. Only sand a little at a
time and check periodically.
You do not want to open the holes up
too much. You will be press
fitting the gauges into the holes so
you want them to fit snug.
