SECTION 1 - WELD BOSS AND OXYGEN
SENSOR INSTALLATION
INSTALLING THE WELD BOSS—AUTOMOTIVE
1 Find a suitable location to install the included
M18 x 1.5mm weld boss on the exhaust system
as shown in Figure A.
On vehicles equipped with catalytic converters,
Dynojet recommends installing the weld boss
before the converters. Vehicles that do not
utilize catalytic converters are free to install the
boss anywhere in the exhaust, but we
recommend keeping it within thirty inches of
the exhaust port.
Turbocharged vehicles have rather high
exhaust gas temperatures and pressures.
In these applications, it is best to install the
weld boss in the down pipe as far away from
the exhaust turbine as possible.
Note: Never install the sensor in the exhaust
manifold between the cylinder head and the
turbo.
2 Mount the weld boss in a manner that reduces
the risk of moisture contamination on the
sensor. Condensation can build up in the
exhaust pipes and potentially damage the
sensor.
98200017.03
3 Ideally, you should orient the weld boss so the
sensor is between the 9 o'clock and 3 o'clock
position (reading clockwise) as shown in
Figure B. A 10° inclination off the horizontal
plane should be considered a minimum.
Note: Verify you have adequate clearance for
the sensor and wiring harness.

NSTALLING THE OXYGEN SENSOR—AUTOMOTIVE
1 Thread the sensor into the weld boss as shown
in Figure C.
Wideband 2 Installation Guide - 3
2 Connect the O2 Sensor to the supplied wiring
harness as shown in Figure D.
Figure DFigure EFigure F
3 Find a suitable location to run the wiring to
the Wideband 2 control module as shown in
Figure E.
Note: Verify the wiring is free and clear of
abrasion and heat sources.
98200017.03
4 Route the wiring through a factory grommet as
shown in Figure F.
If you are unable to find a factory grommet to
pass the wiring through, drill a hole large
enough to accommodate the wiring. Make sure
to use a grommet to protect the wiring.
Note: It is very important that the Wideband 2
Sensor is powered up when the vehicle is
running. The sensor may become damaged if
the vehicle is running and the Wideband 2 is
not receiving power. In the event that you do
not have power running to the sensor, remove
the sensor and install the weld boss plug
included in the Wideband 2 kit.
Note: Running the sensor in leaded fuel
applications decreases the service life of the
sensor.

INSTALLING THE WELD BOSS—MOTORCYCLE
1 Find a suitable location to install the included
M18 x 1.5mm weld boss on the exhaust system
as shown in Figure G.
On vehicles equipped with catalytic converters,
Dynojet recommends installing the weld boss
before the converters. Vehicles that do not
utilize catalytic converters are free to install the

boss anywhere in the exhaust, but we
recommend keeping it within thirty inches of

plane should be considered a minimum.
Note: Verify you have adequate clearance for
the sensor and wiring harness.

2 Connect the O2 Sensor to the supplied wiring
harness as shown in Figure J.
3 Route the wiring to the Wideband 2 module.
Use the supplied zip ties to secure the wire
bundle to the motorcycle.
Note: Verify the wiring is free and clear of
abrasion and heat sources.
Note: It is very important that the Wideband 2
Sensor is powered up when the vehicle is

running. The sensor may become damaged if
the vehicle is running and the Wideband 2 is
not receiving power. In the event that you do
not have power running to the sensor, remove
the sensor and install the weld boss plug
included in the Wideband 2 kit.
Note: Running the sensor in leaded fuel
applications decreases the service life of the

SECTION 2 - WIDEBAND 2 MODULE
INSTALLATION
AUTOMOTIVE
1 The module is robust and water resistant and
can be mounted inside the vehicle or under
the hood. Verify the CAN-Link Ports are
accessible for data transfer.
Note: Install the CAN-Link Expansion Port
seals when the ports are not in use.
2 Mount the module using the supplied dual
lock strips or other suitable means as shown in
Figure K.
When using the dual lock strips, please clean
the surfaces thoroughly with the supplied
alcohol swab.

OTORCYCLE
1 On most motorcycle applications the best
place to mount the Wideband 2 module is
under the seat or in the tail section of the
motorcycle. Verify the CAN-Link Ports are
accessible for data transfer.
Note: Install the CAN-Link Expansion Port
seals when the ports are not in use.
2 Mount the module using the supplied dual
lock strips or other suitable means as shown in
Figure L.

ONNECTING THE GROUND WIRE—AUTOMOTIVE
Connect the black and the black/white wires to a
good ground location with the eyelets provided.
Refer to Figure N.
When using the Analog Input on the Wideband 2,
you may need to run the black/white wire to the
sensor ground. For example, using the Analog
Input to measure TPS voltage, you would tie the
black/white wire to the TPS sensor ground.

Never connect the black wire to a sensor
ground.
Note: Verify the wiring is free and clear of

good ground location with the eyelets provided.
Refer to Figure O.
When using the Analog Input on the Wideband 2,
you may need to run the black/white wire to the

under the hood or in an area that may be
exposed to moisture or dirt.
OPTIONAL CONNECTIONS
SECTION 4 - DIGITAL INPUT (RPM) WIRE
There is one digital RPM input channel built into
the Wideband 2.
1 Locate the white/blue wire in the main harness
as shown in Figure Q.
2 Using a supplied wire-tap, connect the
white/blue wire to the negative side of the
ignition coil.
This provides a stable RPM signal without the
need for a special "tach adaptor".

SECTION 6 - DATA ACQUISITION OUTPUT
W
IRES
The Data Acquisition cable is designed to produce
a calibrated lambda/AFR output voltage that ranges
from 0 - 5 volts.
Your data acquisition device, or flash tuner device,
should have a provision in their software to define
the analog input. Enter the following formula:
(Volts * 1.6)+10 = AFR.
The Data Acquisition cable has two wires as shown
in Figure S:
• violet wire is the 0 - 5 volt signal
• white/violet wire connects to the data
acquisition device ground reference
Note: The white/violet wire is not a ground;
however, it needs to be connected to a ground.
It is important the data acquisition device has
its own ground to the vehicle.
Data acquisition device types are varied. Some may
be grounded by connecting to the vehicle's
diagnostic port. If no other ground exists, you
must run a ground wire from the data acquisition
system to the vehicle chassis ground as shown in
Figure S.

SECTION 8 - ELECTRICAL GAUGE IN VEHICLE
DASH INSTALLATION
A 2 1/16th diameter hole is required for the gauge,
as shown in Figure U, which can be mounted indash or in an aftermarket gauge pod.
The gauge cable must be routed to the Wideband 2
Module and connected to the four pin connector
or to the optional Data Acquisition/Gauge Cable
(P/N 76950118).
When the yellow wire is grounded, as shown in
Figure V, the warning light will turn on and the
alarm will sound. The alarm is selectable with a dip
switch on the back of the gauge.
Apply 12v to the orange wire to dim the
backlighting to nighttime intensity as shown in
Figure V.

ACQUISITION/GAUGE HARNESS INSTALLATION
The Data Acquisition/Gauge Cable (P/N 76950118)
allows you to use the data acquisition output and
one of the optional gauges at the same time. Refer
to Figure X.
Note: Before connecting the Data
Acquisition/Gauge cable, be sure to read and
understand “Section 6 - Data Acquisition
Output Wires”.
The Data Acquisition/Gauge cable has three wires
as shown in Figure X:
• violet wire is the 0 - 5 volt signal
• white/violet wire connects to the data
acquisition device ground reference
• black wire is the ground for the gauge
Note: This black wire is the ground for the
gauge and is not a ground coming from the
module. The data acquisition device needs to
have its own ground to the vehicle.
Data acquisition device types are varied. Some may
be grounded by connecting to the vehicle's
diagnostic port. If no other ground exists, you
must run a ground wire from the data acquisition
system to the vehicle chassis ground as shown in
Figure X.
Refer to the data acquisition documentation for
more information.
