INSTALLATION
1. Check that you have all parts required for installation, and the engine is cool.
2. Disconnect the negative (-) battery cable.
3. Gauge mounts in a 2 1/16” hole. Use supplied brackets and nuts to secure gauge to dash.
4. Drill 1” diameter hole where wires pass through sheet metal (such as firewall) and install rubber grommet provided.
(Grommet will require slit.)
5. Connect the white wire to dash lighting or switchable 12v light source, red wire from harness to +12V terminal on
ignition switch or other +12V power source, and black wire to ground.
6. Reconnect negative (-) battery cable.
PROBE INSTALLATION
1. Begin by installing the thermocouple in the exhaust, then work back to the gauge. Installing the probe in the proper location will
insure optimal temperature readings. For non-turbo engines, install the probe 1-2 inches from the cylinder head.
For turbo engines, remove the exhaust manifold and install the probe 1-2 inches from the cylinder head. If the exhaust manifold
cannotberemoved,installtheprobe1-2inchesaftertheturboexhaustoutlet(Exhaustgastempscoulddropover200˚when
installing after the turbo). CLEAN ALL METAL FILINGS out of the exhaust manifold. Metal filings will damage the turbo impellor
if they go through the turbo.
The probe can be mounted in two different ways, so please use the method best suited for your needs.
A) Pre-existing 1/8” NPT Threaded Hole: Simply screw the threaded fitting into the hole, insert the probe, and tighten the set
screw snugly onto the probe. (Caution: do not over tighten set screw or damage to probe may occur.) Make sure the probe is
oriented so the wires do not come in contact with, or become too close to the manifold or other hot engine parts.
See illustration for details.
B) Stainless Clamp Method: This method is for applications that require frequent removal of the manifold or header for service,
or just faster and easier installation. Drill a 7/16” diameter hole about 6” down from the junction of the exhaust pipe to manifold
junction. Undo the clamp and slide the probe into the hole in the clamp. Slide the set screw collar onto the probe.
Before tightening the collar in position make sure that when inserted, the probe will have its tip in the middle two-thirds of the
exhaust stream. Tighten screw collar in position. (Caution: do not over tighten set screw or damage to probe may occur.)
Hold the clamp open when inserting the probe into the 13/32” hole. Re-join the clamp ends and tighten in position.
Make sure the probe is oriented so the wires do not come in contact with, or become too close to the manifold or other hot
engine parts. See the illustration below for details.
2. With the probe installed, the wire harness can now be routed to the gauge. The wire harness is an integral part of the pyrometer
calibration. It may not be shortened or lengthened without affecting the gauge calibration. You will need to determine a suitable
location to coil the excess wire, and tie it loosely with a wire tie. (Loosely tying the excess coil prevents embritlement caused by
vibration.) Pass the harness through the fire wall using an existing hole, or drill a 1” diameter hole and use the rubber grommet
provided to protect the wire from damage.

Pro Control Active States
The active region for Pro Control outputs are user configurable. For
example, consider a pressure gauge with a low warning set point at
20 PSI . The gauge can be configured so the associated Pro Control
output is active when the pointer falls below the set point [less than 20
PSI] (active low) OR when the pointer is beyond the set point [greater
than 20 PSI] (active high). Likewise, consider a pressure gauge with
high warning set point at 95 PSI. Again, the gauge can be configured
so the associated Pro Control is active when the pointer falls below
the set point [less than 95 PSI] (active low) OR when the pointer
progresses beyond the set point [greater than 95 PSI] (active high).
To change the active state:
With power off, press and hold the PEAK button. Apply power to the
gauge. Release the PEAK button. Press and release the WARN
button. The gauge is now in Active State Set Mode. The pointer will
point straight up at the value in the top center of the dial. Press and
release the WARN button to toggle back and forth between the low and
high warning point active state modes. Doing so will cause the dial to
change back and forth between green and red. When setting the low
warning active state the dial face will be green. When setting the high
warning active state the dial face will be red.
Once the designated warning mode is selected (green or red) press and
hold the WARN button to toggle between active high and active low. As
you hold the button the pointer will continuously sweep from the left of
center and to the right of center pausing at each side. Left of center is
active low and right of center is active high. Release the WARN button
when the pointer is in the position of the desired active state. Once you
have selected the desired state, don’t press any buttons for about three
seconds. The dial will flicker white several times to indicate the desired
setting has been saved and the gauge will return to normal operation with
your new state selection. State selections are saved when power is off.
NOTE: The Pro Control Active State does not
affect the color of each dial region.
Pro Control
The Pro Control feature activates a switched ground output at a user defined set point. Pro Control can be used to switch on a relay to activate
ignition kill, cooling fans, lamps, alarms, etc. The set points define three regions on the gauge dial, the region below the low set point, between the
set points, and above the high set point.
