INSTALLATION INSTRUCTIONS
OXYGEN SENSOR KIT FOR AIR / FUEL
RATIO MONITOR
MODEL 2244
®
Instr. No. 2650-838C
Installation
1. Drill 7/8" diameter hole in exhaust pipe.
2. Weld in oxygen sensor boss.
3. Apply a small amount of the enclosed anti-seize compound to the
sensor threads ONLY. Contact with the sensing element can cause
damage and shorten its life expectancy.
CAUTION: Anti-seize compound may cause skin or eye irritation.
Wash skin after use. For eye contact flush with water. If swallowed,
DO NOT induce vomiting. Contact a physician.
KEEP OUT OF REACH OF CHILDREN.
Black Wire: Connect to good engine ground.
Violet Wire: Connect to violet wire on air / fuel ratio monitor.
Install oxygen sensor in a spot where exhaust from all cylinders flows
past it, but also as close to the cylinder head as reasonable. This will
allow the sensor to reach 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. Installation 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 sensors.
Note: Use boss plug when operating engine without oxygen sensor.
5. Plug in wiring harness and connect as shown below.
Note: Red and black wires are for the oxygen sensor heater. The
heater reduces the oxygen sensor warm up period.
Warning: Do not connect ohm meter to oxygen sensor or touch
violet wire to ground or power. Damage to oxygen sensor will result.
If a meter is to be used, only use a high impedance (10 mega ohm
or higher) digital multimeter.
Fouling and/or permanent damage to the oxygen sensor over time will
result if used with any of the following:
• Leaded gasoline and fuel additives containing lead
• 2 cycle gasoline (gas/oil mix)
• Diesel fuel
• Nitromethane
• Excessively rich mixtures
If the air / fuel ratio monitor responds sluggish, the oxygen sensor is
probably partially fouled, and should be replaced.
Note: The oxygen sensor must reach at least 600˚ F before an
accurate signal is produced. The oxygen sensor will require a
short warm up period after the engine is started, this is usually
less than one minute.
