Installation
1. Disconnect the negative (-) battery cable.
2. Gauge can be mounted in a 2
1 ⁄
16
" dia. hole with brackets supplied.
Gauge can also be mounted in Auto Meter Mounting Cup, or in
Auto Meter Gauge Works Pods.
3. Wire gauge as shown.
Red Wire: Connect to a fused and switched 12V positive source
that is turned on and off with the ignition switch
Black Wire: Connect to good engine ground.
Violet Wire: Connect to oxygen sensor signal wire. Connect to
vehicle wiring harness, not oxygen sensor since some oxygen
sensors use shielded wire.
If your vehicle is not originally equipped with an oxygen sensor,
purchase Auto Meter model number 2244. The heated oxygen
sensor comes with a weld in boss, boss plug, and wiring harness
with a weather pack connector. The oxygen sensor should be
installed in a spot where exhaust from all cylinders flows past
it. The oxygen sensor should also be installed as close to the
cylinder head as reasonably possible so that the sensor reaches
operating temperature quickly. If headers are used, the oxygen
sensor should be installed in the collector. If cast iron manifold(s)
are used, install the sensor in the pipe just below the manifold.
Mounting in the left or right side is acceptable. If monitoring of
both sides is desired, a second oxygen sensor can be used and
a switch (purchased locally) can be wired to toggle back and forth
between both sensors.
The Air / Fuel Ratio Monitor can be used with the following fuels.
fuels
Unleaded Gasoline
Methanol
Ethanol
Propane
Stoichiometric Air / fuel Ratio
14.7:1
6.5:1
9.0:1
15.7:1
OK for use with Nitrous Oxide.
The Stoichiometric Air / Fuel Ratio is the chemically correct
ratio where theoretically all of the oxygen and all of the fuel are
consumed. The mixture is neither rich or lean.
