iMFD Sensor Module SM-EGT

*Please read the instructions completely through at least once before proceeding with the

installation to minimize errors.

*Double check polarity of power before powering it on for the first time.

Overview:

(Figure 1)

1. Connects to 12V-18V power source.

2. Analog outputs (0-5V linear output)

3. Termination jumper. Closed for first SM in iMFD daisy chain.

4. Connects to next SM in iMFD daisy chain or to first DM

5. Connects to previous SM or unconnected if first SM in iMFD daisy chain

6. Connects to K Type thermo coupler.

Install the Exhaust Gas Temperature Sensor:

1. Install the temperature probe on your header approximately 6-12 inches away from the engine block for best performance.

2. The PLX EGT K Type thermo coupler probe screws into a 1/8 NPT tap.

3. BE CAREFUL, DO NOT OVERTWIST the EGT probe’s wires during installation. This can cause the insulation to come loose

and short the wires internally.

4. Mate the EGT probe with the SM-EGT module where indicated K-Type T.C.

Connecting Power to the Unit:

CAUTION! CONNECTING THE SM-EGT IN REVERSE POLARITY WILL

DAMAGE THE UNIT! CHECK CONNECTIONS BEFORE POWERING ON.

1. The SM-EGT accepts 12-18V DC for power. Connect the negative wire (black) to your vehicle’s ground. This is usually the

negative terminal of your automobile’s battery. Connect the positive wire (red) to your vehicle’s ignition power. This power

is only supplied when your key is turned passed a specific position and is off when your key is removed. Your power

connection must be capable of supplying at least 1 amp of current. A 5 Amp fuse is recommended for safety.
