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
ensure optimal temperature readings. For non-turbo engines, install the probe 25mm-50mm from the cylinder head.
For turbo engines, remove the exhaust manifold and install the probe 25mm-50mm from the cylinder head. If the exhaust
manifold cannot be removed, install the probe 25mm-50mm after the turbo exhaust outlet (Exhaust gas temps could drop over
100˚C when installing after the turbo). CLEAN ALL METAL FILINGS out of the exhaust manifold. Metal filings will damage the
turbo impeller 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
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 below 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 11mm diameter hole approx. 150mm 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 11mm 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 25.4mm diameter hole and use the rubber
grommet provided to protect the wire from damage.

Power-Up
The pointer will move backward to the stop pin and then display actual temperature. This procedure is an auto-calibration function and is
performed on every power-up. While this test is being performed, the gauge may make a clicking sound. This is normal.
