● Carefully read the "Before Installation" and "About Installation and Operation" sections of the manual concerning installation
and operation. Then install the product properly and safely. Installation in an unsuitable location or improper installation can
result in the product falling from its position or damage to the vehicle.
Installation (for installation personnel)
STEP１ Wiring power supply wire and signals
Warning
● When installing the display, be sure to follow the instructions of the Defi-Link Control Unit II(or the Defi-Link Control Unit).
● Do not pull the wires out of connectors forcefully. The
connectors may be broken and the wires may be cut.
When pulling out the wires, press the lock firmly and
unclip the locks of connectors.
1) Connect the power supply wire to the vehicle with solderless connectors【Figure1】.
2) Connect the other side of the power supply wire to the DC SOURCE connector of the D.C.Unit.
※ There are two DC SOURCE connectors. Both connectors are usable.
3) Connect the speed & tacho signal wire(green & blue wires) to the speed and tacho signal wire of the engine control
unit(ECU) with solderless connectors【Figure2】.
4) Connect the other side of the speed & tacho signal wire to the SPEED&TACHO connector of the D.C.Unit.
※ In the case where this product is linked to the Defi-Link System afterward, connect the white wire of the power
supply wire to the illumination wire(12V wire when small lamp is on). Connect the tacho signal wire to the
Defi-Link Control Unit II(or the Defi-Link Control Unit【Figure3】.
1) Disconnect the previously connected power supply wire from the Defi-Link Control Unit II(or the Defi-Link Control Unit).
2) Connect the disconnected power supply wire to the DC SOURCE connector of the D.C.Unit.
※ There are two DC SOURCE connectors. Both connectors are usable.
3) Connect the DC SOURCE connectors of the Defi-Link Control Unit II(or the Defi-Link Control Unit) and the D.C.Unit
using the attached power supply link wire.
4) In the case where a meter wire is already connected to the METER OUTPUT１ connector of the Defi-Link Control Unit
II(or the METER connector of the Defi-Link Control Unit), disconnect the meter wire. (If the METER OUTPUT1
connector of the Defi-Link Control Unit II is not in use, skip the next procedure and go to 6.)
5) Connect the disconnected meter wire to the LINK connector of the D.C.Unit.
※ There are three LINK connectors. All three connectors are usable.
6) Connect the METER OUTPUT1 connector of the Defi-Link Control Unit II and the LINK connector of the D.C.Unit using
the attached meter wire. (Connect the METER connector of the Defi-Link Control Unit and the LINK connector of the
D.C.Unit using the attached meter wire.)
※ There are three LINK connectors. All three connectors are usable.
7) Connect the attached tachometer signal wire(blue) to the tacho signal wire of the engine control unit（ECU) using the
attached solderless connector. In the case where a tachometer signal wire(blue) is already connected to the Defi-Link
Control Unit II(or Defi-Link Control Unit), skip this procedure. Leave the tachometer signal wire(blue) and go to 9.
8) Connect the other side of the tachometer signal wire to the TACHO connector of the Defi-Link Control Unit II(or the Defi-
Link Control Unit).
※ Be sure to connect the tachometer signal wire(blue) to the TACHO connector of the Defi-Link Control Unit II(or the
Defi-Link Control Unit). If the tachometer signal wire(blue) is connected to the D.C.Unit not to the Defi-Link Control
Unit II(or the Defi-Link Control Unit), the engine speed will not be displayed.
9) Connect the green wire of speed & tacho signal wire(speed signal) to the speed signal wire of engine control unit(ECU)
using the attached solderless connector.
※ The blue wire of the speed & tacho signal wire does not need to be wired. Insulate and bind up the wire so as not to
interfere with driving【Figure2】.
10) Connect the other side of the speed & tacho signal wire to the SPEED＆TACHO connector of the D.C.Unit.
Caution
STEP２ Check Wiring
1) Connect the display wire of the Defi-Link VSD X to the DISPLAY UNIT connector of the D.C.Unit.
2) Check that all the wires are properly connected.
3) Turn on the ignition of vehicle and make sure the display is lighted.（The display looks inverted on the display unit.）
4) If the display is lighted, go to the next step. If not, go back to STEP1 and rewire.
