Gauge Mounting
AIR / FUEL RATIO GAUGE
INSTALLATION INSTRUCTIONS
this gauge was designed for 12-Volt, negative
ground electrical systems.It works with 1-wire,
2-wire, 3-wire, and 4-wire oxygen sensors. If your
vehicle is not equipped with an oxygen sensor, an
oxygen sensor kit can be purchased and installed.
Install the sensor in a location where the exhaust
streams from all cylinders meet and as close as
possible to the cylinder head.
PRECAUTIONS
1. read the entire instructions before proceeding.
2. route all wiring away from linkages, engine
parts that become hot, or moving parts.
3. never smoke while working on your vehicle and
always keep a fire extinguisher nearby. It should
be rated for gas/chemical/electrical fires.
4. never lay tools on top of the battery or wear
jewelry during electrical work to avoid severe
shorts.
5. do not touch the wire(s) coming from the
oxygen sensor to power or ground. do not
use ohmmeter on these wires. either of these
actions will damage the sensor.
INSTALLING GAUGE
this gauge can be mounted into a surface of your
choice or into a gauge pod.
1. It is recommended that the battery ground cable
be disconnected before any electrical work is
performed.
2. Choose a location to mount the gauge where it
will be viewable from a normal driving position.
3. If you are installing the gauge into a surface (for
example the dashboard) make a 2-1/16” hole
for the gauge. be sure to check for wires behind
dash. do not accidentally cut any wires or hoses.
be sure there is clearance around the hole for
the gauge mounting bracket.
4. Plug the wire harness connector into the
receptacle on the back of the gauge.
5. Insert the wires and the gauge into the mounting
panel or hole.
6. Install the mounting bracket and tighten the
knurled nuts lightly.
7. Position the gauge for best visibility and tighten
the knurled nuts with moderate pressure.
HOOkING UP WIRES
1. Verify that the battery ground cable is
disconnected before any electrical work is
performed.
2. Connect the red wire to a fuse protected source
of +12 Volts turned on and off with the ignition
key. the fuse box is usually a good place to
start.
3. Connect the white wire to a circuit which is
energized by the headlamp switch or to the tail
light circuit.
4. If desired, drill a 3/8” hole in the firewall, install a
rubber grommet (provided), and feed the black
and green wires through the grommet into the
engine compartment.
5. CONNECT THE bLACk WIRE TO A GOOd
ENGINE GROUNd SOURCE. dO NOT
CONNECT bLACk WIRE TO GROUNd
POINTS UNdERNEATH THE dASH OR
ON THE bOdy. FINd A LOCATION ON
THE ENGINE bLOCk. CLEAN RUST ANd
PAINT IF NEEdEd bEFORE MAkING THE
CONNECTION. USE THE RING TERMINAL
(PROvIdEd).
6. Connect the green wire to the signal wire
between the oxygen sensor connector and
the car computer. do not connect to the wire
between the oxygen sensor and the connector,
as this wire is often shielded. refer to diagrams
below for selecting the correct connection
point. If the oxygen sensor has 2, 3, or 4 wires,
consult wiring diagram for your vehicle or
contact vehicle manufacturer to identify the
signal wire.
