Model No. : L-TR68B

1. The L-TR68B is a 2-way security system featured with remote engine start and can be

installed to work with any vehicle with its normal voltage of 12 volt.

2. The L-TR68B’s circuit is designed to suit both the manual gear and the auto-transmission

gear car for remote engine starting.

3. The L-TR68B has 2 different engine start time circuit for remote starting of both gasoline

engine and diesel engine.

Installation of the major components

Choice of place for main control module

Install this behind the dashboard at the suitable position, near the ignition cylinder (within 60 cm

from it) but far from the heat source and water tank.

l Siren

Choose its location in the engine compartment [far from the heat source and water tank, and free

from the

engine’

s moving parts]. Drill a hole of 1/8 in drill at the selected place and secure the siren using

the mounting bracket, facing the siren downward or in the horizontal position.

l Hood switch

While in arm mode or remote engine running, this helps the main control module detect the

hood’s status .It must be installed on the grounded metal surface. Drill a hole of 1/4 inch at the

selected place and secure the hood switch and adjust it. [The switch must have negative output

when the hood is opened, and becomes neutral when the hood is closed.]

Dash LED Status indicator

During the security standby mode, this performs as a visual indicator against attempted theft and

also is the current status indicator of the system. During programming of system features, the

LED’s flashing pattern provides feedback as a confirmation for different active modes being

achieved. Mount the LED at a suitable area to ensure better visibility either from inside or

outside of the vehicle.

Override switch

System’

s programming can be done using override switch as in the manual entry into valet mode,

manual arm/disarm. It may not require concealment because the main system itself has other

multi-security features. Then connect it with the system’s modules for valet switch.

RF transmitter module/ call button This is integral part of the main system for transmitting / receiving and paging by push button. Select its mounting place to insure the best transmission range. It is suggested to fix it on the left or right upper area of the interior side of the windshield, using the double stick tape included. Be sure not to block driver’s view. Anti –carjack switch While ignition “ON”, entry and exit of anti-carjack mode can be done by this switch.

with wire from the start motor. The installing details are as below： ※ This kind of connection will enable the start kill during alarm trigger. 2. Blue wire: output connecting wire for ACC This provides the current needed by ACC. Locate the wire of the ignition switch area that shows (+) 12 v when the ignition key is turned to “ACC” and “ ignition” position . Connect this wire with the blue wire. But this wire must be “0” volts when the ignition key is turned to “ start” position. 3.

6. Green wire: output connecting wire for ignition # 2 Locate the wire of the ignition switch area that shows (+) 12 v when the ignition key is turned to “ ignition” and “start” . Connect this wire with the green wire. Note：In some vehicles, this wire shows “0” volts while the engine is starting or cranking. But in some vehicles, this provides +12 v current. Program this as required. [ Refer to RF Features Program Table 1, line 7th ] 。 l THE 18 PIN INPUT/OUTPUT HARNESS WIRE 1.

C TYPE: For the vehicle with no dome light, an additional relay is required. The installing details are as below.[Refer to RF Feature Program Table, line 14 th for setting at 6sec] 3 Black w/ Red trace wire: ignition # 3 or bypass V.A.T.S. (-)output at 300ma While the system is in remote engine start mode; this feeds (-) 300ma current. Some vehicles need this circuit for the engine running .If there is no such device, an additional relay is required for the control of light.

When the remote transmitter activates this channel, this feed (-) 300ma output which, needs an additional relay, to control the device as required. Note: Refer to RF Features Program Table , line 4th for programming. 6 Grey w/ Black trace wire: tachmeter input singal This wire diagnoses the success of engine start done by the remote control unit. Locate the signal wire of the tachometer.[ Use the multi-meter adjusting for the measurement DC voltage.

If the door switch is（+）trigger, connect this with the Blue w/ Red trace wire. If the door is（－） trigger, leave the Blue w/ Red trace wire unconnected. 8 Orange w/ White trace wire: trunk switch (-) trigger input If the trunk switch is （－）trigger, connect trunk switch pin with the orange w/ white trace wire. 9 Black wire : ground(-) This wire supplies current for the main module and needs to be grounded on a stable metal surface in the installation.

Connect this wire with the red wire of the siren or use an additional relay to connect with the original horn. ※ (Refer to RF Features Program Table , line 6th ) 14 Yellow w/ Blue trace wire: for Active channel #3 or 2 stage door lock output (-) 300ma One of the options can be chosen as required. (a) active channel # 3 and (b) 2 stage door unlock [ for 1s t stage to open the driver’s door and for 2nd stage to open all other doors].

16 Orange/violet trace wire: Wire for hand brake (or) rear brake light (- ) 300ma input There must be a negative current during the remote engine starting for the main system to allow for the remote engine start. While starting the engine remotely , if there is not any negative current on this wire the engine immediately shuts down. There are 2 options for this wire connection.
PAGE 10
Connect the orange w/ gray trace wire with hood switch’s output wire. When the hood is closed this wire provides “0” current and the main system allows engine start. When the hood is opened, this wire feeds (-) output. The main system will not allow engine start。 2 s black PIN for switch-controlled anti-carjack 1.
