5  Check the thread size of the port being used. Use included adapter bushings, if required.
Temperature sensor threads are ⅛” NPTF.
 Many Emission Control Devices are connected to temperature sensors or switches. Be careful not
to disable these when installing a sensor.
 If an adapter bushing is necessary, do not “bottom out” or close the gap when installing sensor
into adapter bushings on units with tapered threads.
6 Thread the sensor into the adapter bushing (if used) finger tight, then thread the sensor into the port
finger tight. Next, tighten with a wrench approximately one half turn. If leakage occurs at the sensor,
tighten one-quarter turn at a time until leakage stops. If necessary, thread sealant such as Teflon tape
may be used.
 When using a torque wrench, tighten approximately 20nm/15 lb-in. or slightly more, if leakage
occurs. Do not use the body of the sensor to tighten! Use only the hex and the correct wrench. Do
not over tighten!
7   Connect the temperature sensor to the temperature sensor harness by pressing the connector
into the slot.

bushing.

8   Connect Axle Temperature gauge to the ESP. (See ESP instructions for more details on how
to do this). Note: If drilling a mounting hole in a panel to mount this gauge, the hole size should be
2.040”.
9  Secure all wiring so that it does not interfere with moving parts or chafe on sharp edges. This may
be accomplished by routing the wiring within the factory wire harness sheath, using wire ties and
sheathing, and using appropriate grommets when passing through the firewall.
