4x4/EX (-)
•
The 4x4 terminal can be used on four wheel drive vehicles. The 4x4 input is activated by a
ground signal from a switch on the transfer case. Connect a wire from this terminal to the
switch on the transfer case. Whenever the 4x4 input is grounded and the 4X4 label has not
been changed from factory default, a yellow 4x4 indicator will be shown on GRAFIX Instrument
Cluster. The Message Area will indicate the
“4x4” terminal has been activated. This 4X4 input
can also be set with a custom label for other uses or used for Door Open, as configured in the
MAIN-SYSTEM-DISPLAY-EXTRA LABEL setup menu.
RIGHT (+)
•
The RIGHT terminal is activated by a 12 volt signal from the turn signal flasher. When this
terminal has 12 volts, a green arrow will light up on the GRAFIX Instrument Cluster. An
existing wire from the vehicle for the right turn indicator can be used or a new wire can be
connected from the turn signal flasher or power wire feeding the right turn signal bulb. This
terminal is also monitored by the turn signal reminder. If the turn signal remains active for
more than ¾ mile, a warning message will be shown.
LEFT (+)
•
The LEFT terminal is activated by a 12 volt signal from the turn signal flasher. When this
terminal has 12 volts, a green arrow will light up on the GRAFIX Instrument Cluster. An
existing wire from the vehicle for the left turn indicator can be used or a new wire can be
connected from the turn signal flasher or power wire feeding the left turn signal bulb. This
terminal is also monitored by the turn signal reminder. If the turn signal remains active for
more than ¾ mile, a warning message will be shown.
HIGH (+)
•
The HIGH terminal is activated by a 12 volt signal from the headlight high beam wire. When
the terminal has 12 volts, a blue high beam indicator will light up on the Instrument Cluster. An
existing wire from the vehicle for the high beam indicator can be used or a new wire can be
connected from the high beam side of the high/low beam switch.
BRAKE (-)
•
The BRAKE terminal can be used as a brake system warning indicator. The BRAKE input is
activated by a ground signal from the brake pressure switch on the master cylinder or from the
parking brake set switch. Connect a wire from this terminal to the pressure switch on the
master cylinder or consult a vehicle service manual to determine color and location of an
existing wire. Whenever the BRAKE input is grounded, the system will display a red
exclamation indicator on the GRAFIX Instrument Cluster.
ENGINE (-)
•
The check engine terminal is used with fuel
injection ECM’s to indicate engine problems and
trouble codes. The ENGINE input is activated by a ground signal from the ECM. Whenever
the check input is grounded, the system will display a red check engine indicator on the
Instrument Cluster.
•
For certain ECM
’s, when placed into diagnostic mode, trouble codes can be read by counting
the flashes of the check engine indicator. Consult a service manual for the fuel injection
system that you have for further information on trouble codes or if that is how your system
operates. With s
ome ECM’s, a 12 volt light bulb may need to be connected in addition to the
ENGINE input in order to provide proper current loading. In this case, both the bulb and our
Instrument Cluster
’s indicator would come on when the check engine wire is “active”.
Note: The GRAFIX system will not generate any error codes or display the error codes
from the ECM. It will only indicate that an error has occurred by illuminating the
ENGINE symbol on the Instrument Cluster.
