1. Disconnect the negative battery cable.
2. Mount the controller inside the vehicle away from heat, water,
moisture, dirt and all moving parts, in an easily accessible location.
This allows for the unit to be accessible should calibration need to be
performed.
3. Install the provided LSU 4.9 Sensor by welding the matching
exhaust bung to the exhaust pipe.

Note: We recommend using Anti-Seize on the bung threads so
that you can unscrew the sensor when necessary.

Note: Make sure the location of the bung is a minimum of 6
inches after the exhaust ports, but before the catalytic converter,
and no more than 36 inches from the last exhaust port.

Note: The bung must be installed to the top or side of the
exhaust pipe at a minimum of 10 degrees for the top and 15
degrees for the side from a horizontal position with the
electrical connection up to prevent a collection of liquid at the
element during the warm up phase.
4. Next, route and secure the sensor wire harness from the sensor into
the vehicle, close to the controller’s location. Be sure to use a
grommet when routing the wires through the firewall to protect them
from stripping.
5. Connect the red wire to a positive 12 volt constant (un-switched)
source either directly to the battery or to a fuse panel on the vehicle.
If wiring to an un-fused source, install a 3 amp fuse inline within 20
inches of the sources connection.
6. The white wire should be connected to a positive 12 volt ignition
(switched) source. It may be connected to the fuse panel, an accessory
wire, or any positive 12 volt source that turns on and off with the ignition
7. Connect the black wire to any good (unpainted) ground connection.
You may also route a wire directly to the negative side of the vehicle’s
battery.
8. The Night Time Dimming feature decreases the brightness of the gauge
face by 30%. Connect the orange wire to the 12 volt positive headlamp
source. This allows the mode to be activated when the headlights come
on. This step is optional and will not affect operation of the gauge if it is
omitted. NOTE: Do not connect the orange wire to a dimmer wheel.
This will cause the gauge lighting to flicker.
9. Reconnect the negative battery cable.
