TURBO BOOST PRESSURE GAUGE AND
SENSOR INSTALLATION INSTRUCTIONS
I C O N K E Y
CAUTION
Tools may be required
Shown in picture
1
Disconnect batteries. Do not reconnect battery power until system
is fully configured to avoid risk of shock or fire.
2
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.
3
Install the new sensor. Pressure sensor threads are ⅛” NPTF.
Many Emission Control Devices are connected to OEM sensors or switches. Be careful not to
disable these when installing a sensor.
4
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!
5
Connect the pressure sensor to the pressure sensor harness by pressing the connector into
the slot.
Figure 1: Pressure sensor and harness.
6
Route the sensor harness to the intended gauge mounting location, using grommets as appropriate
when passing through the firewall. Connect the sensor harness to the gauge connector as follows:
7
Trim wires to desired length. The red/yellow, green, and black wires are the +5V, sensor,
and ground connection, and connect to cavities 4, 5, and 6 of the orange connector respectively (see
Figure 2).
Install the three wires into the insulation displacement connector (orange connector). Carefully
lay the wires across the connector cavities, hold the connector steady with a vice or pliers and press
the wires into each cavity with a small screwdriver. Each wire must be pushed completely to the
bottom of its groove in the connector, to ensure a good electrical connection. Note that the 3
sensor harness wires run only between the gauge and the sensor, not connecting to any other power
or ground.
