02 SENSOR INSTALLATION

1. The following steps describe the proceedure

for the installation of the 02 sensor, bung and

pigtail routing. Specic layouts may vary on

your application.

1. Turn o the ignition and disconnect the negative

battery cable. Jack up the car and place on suitable

stands to enable access to the exhaust system.

2. Find the best suitable location to install the O2

sensor. It is recommended that the sensor be 6” to

10” after the point where the individual cylinders

merge and placed between 10 and 2 o’clock

position, (SEE DIAGRAM ON PAGE 8). It is also

recommended that there be at least 18” of exhaust

pipe after the sensor. Mark the desired sensor

location for drilling. If your vehicle is equipped

with catalytic converters, The O2 sensor should

be mounted between the engine and the catalytic

converters. It is critical that the O2 sensor is NOT

mounted on the bottom of the exhaust to prevent

condensation from entering the sensor. Verify the

O2 sensor cable is away from any heat source to

prevent damage to the cable.

NOTE: See diagram on page 8.

4. Weld the provided O2 sensor tting into the

exhaust pipe.

NOTE: The exhaust pipe was removed for

illustration. It may be necessary to remove the

exhaust pipe to perform this step.

3. Drill a ¾”id hole in the marked location. Deburr

the hole after drilling.

NOTE: The exhaust pipe was removed for

illustration. It may be necessary to remove the

exhaust pipe to perform this step.

5. Install the provided O2 sensor into the tting.

NOTE: Apply anti-sieze compound to threads.

6. Connect the O2 sensor pigtail into the ECI wiring
