Installation
choose a suitable location under
the lower edge of the dash panel
for mounting the instrument
panel, or on top of the dash for
the molded instrument console.
Be certain the instruments can be
viewed conveniently by the driver.
UNDER DASH: Using the panel as
a template, drill two
3 ⁄
16
” diameter
holes in the dash and mount
the panel with two No. 10 x
1 ⁄
2
”
machine screws, nuts, and star-
washers provided.
ON TOP OF DASH: Wipe the dash-
top with an alcohol pad or other
surface cleaner. Remove the
backing from the adhesive Velcro
tape on the bottom of the console
adapter, position the console
adapter and press down firmly.
Once the gauges are wired and
secured to the console according
to the following instructions,
attach the console assembly to
the console adapter using the two
machine screws provided.

sensor location
Maximum allowable exhaust gas
temperatures for diesel engines
can vary substantially, depending
on the engine and turbocharger
configuration. Refer to the Owners
Manual for your Banks system to
determine maximum temperature
specifications for your specific
application.
There are two methods of exhaust
gas temperature measurement
on turbocharged engines. Both
methods are accurate if done
properly, but will commonly differ
by as much as 300°F on the same
engine.
TURBINE INLET TEMPERATURE:
Measured in the exhaust stream
before the turbine wheel of the
turbo (in the exhaust manifold).
The tip of the pyrometer sensor
should not contact the metal
surface of the manifold.
TURBINE OUTLET TEMPERATURE:
Measured in the exhaust stream
after the turbine wheel (in the
turbine outlet pipe). The pyrometer
sensor should be located as
close to the outlet of the turbo as
possible.
Chevrolet/GMC 6.2l/6.5l
diesel, naturally aspirated:
Locate a portion of the thin-walled
exhaust tubing that is easily
accessible with a drill and as close
to the engine as possible (not in
the actual manifold).
Drill a 5 ⁄
16
” hole in the exhaust
tubing. Weld the 1 ⁄
4
” NPT bung
provided to the pipe centered over
the hole. Install the pyrometer
sensor into the bung.
Chevrolet/GMC 6.2L/6.5L diesel
with Banks Sidewinder turbo:
Install the threaded pyrometer
sensor into the
1 ⁄
4
” NPT threaded
hole in the right exhaust manifold.
Use anti-seize compound on the
threads. See Figure 1.
Chevrolet/GMC 6.5l diesel
with factory turbo: TURBINE
INLET TEMPERATURE: Disconnect
both the compressor inlet and
outlet hose joint connections.
Loosen the V-band at the turbo
outlet, the four bolts/nuts at the
turbine inlet and the two bolts in
the oil drain flange. Remove the
turbo from the engine.
