Innovate Motorsports MTX-D, Boost/Shift Gauge - Manual (Page 4)

- 4 -
Circuits that share power with the vehicle’s stereo, ignition system, and fuel pump
are not recommended.
2. Connect the main BLACK wire to a ground source. Note that there are other black wires
coming out of the 2 pin and 3 pin connectors, these are not the main gauge grounds. Avoid
noisy ground sources, such as grounds used for the radio and or ignition.
3. Connect the WHITE wire to a headlight power wire (a wire that supplies current when the
headlights are on). This enables the display to dim for better nighttime viewing. DO NOT
CONNECT THIS WIRE TO THE HEADLIGHT DIMMING WIRE. Connection to this rheostat
type of switch will cause the gauge to malfunction. If you chose not to utilize the dimming
feature, connect this WHITE wire to ground.
2.2 MAP sensor wiring
1
Fish the MAP sensor’s three pin connector through the firewall and to the MTX Boost/Shift
gauge.
2 Connect the sensor’s male three pin connector to the female 3 pin connector on the gauge.
3 Coming out of the female three pin connector you will find a black wire with a stripped end.
Connect this black wire to the same ground source as the gauge.
2.3 Tach signal wiring
1. The two pin connector with a red wire is the tach input for the shift light. A tach signal can
be acquired from the negative lead of a coil, ECU, negative lead of an injector, or ignition
box (i.e. MSD 6AL). Connect the tach signal to the red wire of the 2 pin connector
extending the wire as needed.
Note: Ignitions running a multi-spark setup (i.e. MSD 6AL) must use the provided tach signal
from the ignition box.
A tach signal can not be acquired from the negative lead of the coil on vehicles
with CDI ignitions. For these applications use the negative lead of an injector or a tach
adapter (if available for your model ignition).
2. Connect the sensor’s male two pin connector to the female two pin connector on the
gauge.
3. Coming out of the female two pin connector you will find a black wire with a stripped end.
Do not use this wire, isolate and tuck it away.
3 Programming the Gauge (LM Programmer)
The MTX Boost/Shift gauge is programmable with the following functionality:
1. Change the display unit of measure from Imperial to Metric
2. Configure the RPM pulses per rotation
3. Setup alarms and warnings
4. Setup shift light modes/parameters
5. Upgrade the firmware
