4 Find a location where boost pressure can be measured such as an existing port on the intake, or cut the
MAP (Manifold Absolute Pressure) line and insert a Tee fitting (obtain from your local automotive
supply store). If there is an M8 x 1.25 intake bolt exposed to intake pressure, it can be replaced with
R7741, a hollow boost bolt for 1998.5 - 2006 Dodge models. Alternatively, drill and tap the intake
elbow for ⅛” NPTF.
5 Install the new sensor. Pressure 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.
6 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 pressure sensor to the pressure sensor harness by pressing the connector into the
slot.
Figure 3: Pressure sensor and harness.
8  Connect boost 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.
