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. Using automotive grade wiring (18 gauge), 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.
 If wiring to an un-fused source, install a 3 amp fuse
inline within 20 inches of the sources connection.
You may obtain an optional “add a circuit”
accessory. This component easily fits into your fuse
panel and provides an additional fused power wire
for accessories such as gauges. This is available at
www.GlowShift.com or a local auto parts store.
4. 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.
5. 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.
6. The orange wire should be connected to a positive 12 volt
switched source (head lamp). This controls the dimmer
function to dim the gauge brightness by 30%. This step is
optional.
7. Install the provided LSU 4.9 Sensor by welding the
matching exhaust bung to the exhaust pipe.
 Make sure the location of the bung is no less than a
minimum of 18 inches after the exhaust ports, but before
the catalytic converter. The bung must be positioned in
such a way that the sensor is at a minimum of 10
degrees from a horizontal position with the electrical
connection up to prevent a collection of liquid at the
element during the warm up phase. SEE DIAGRAM
ABOVE.
8. 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.
9. Reconnect the negative battery cable.
