L2630-WIRE Install Guide

The DTC-3G-L2630-WIRE package comes with the GPS device, and a fused wiring harness with wires that attaches through the 20 pin connector.

Vehicle Placement of L2630-WIRE

The L2630-WIRE has a built in antenna that allows the LMU to be installed in the dash or under the steering column, near to the vehicle wiring. Since GPS signals are very low power, any metal blockage of the unit can prevent it from obtaining a valid GPS fix.

The best places for good GPS reception are on top of the front or rear dashes. If a covert installation is preferred, it is best to install inside the front dash, provided that there is no metal in the dash that would prevent GPS reception.

The LMU 2630 is not weather sealed so the area it’s installed in should be free of water and dust.

 

Connecting Power, Ignition, Ground and Input(s)

The power input (red wire) must be connected to a constant (un-switched) +12 VDC or +24 VDC supply; preferably connected directly to the vehicle battery terminal or as close to it as possible.

This connection point should be fuse protected to not more than 5 Amps. The included wiring harness has fused red and white lines rated to 3 Amps.

The ignition input (white wire) must be connected to the vehicle ignition or another appropriate key operated line, ensuring that power to the ignition wire is available only when the vehicle ignition is on.

The ground line (black wire) must be connected to chassis ground.

Failure to connect the power lines in the manner described may result in discharge of the vehicle battery.

For best results, it is strongly recommended that the LMU connection be on its own circuit. Connect the power input directly to the vehicle battery if possible and protect the circuit with an inline fuse. If you must connect through the fuse box, use standard commercial wiring practices to create a permanent installation rather than using press-in fuse clips or other temporary measures.

The L2630-WIRE also has 2 LED lights that can be used for diagnostic purposes after installing.

Green light - GPS - solid after it has successfully obtained a valid GPS fix.

Orange light - Cellular - solid after it has successfully connected to the cellular network.

Both lights must be showing solid to declare a successful installation.

 

Input Wiring - Optional

When determining what inputs to use for installations, it doesn’t matter what you connect to what input, but you must be consistent across your fleet. If you decide to install the hood sensor on input 1, that should be installed the same for all other vehicles. This consistency means your reports and notifications will always indicate input 1 is the hood sensor.

Let FLEETBridge customer service know what’s connected to what input so that the text of your input notifications can be customized. For example, the notification will show “Hood Open” instead of “Input 1 low”.

The inputs are normally biased high and must be connected to ground when the trigger is required.

The L2630-WIRE has 3 input wires in the harness. The harness is labeled with pin 1 and 20 to determine the pin connections.

 

Input 1 – Solid Blue Wire – Pin 3

Input 2 – Orange Wire – Pin 12

Input 3 – Violet Wire – Pin 6

 

Input Logic:

Input Low: Trigger On

Input High: Trigger Off

Temperature Wiring

 

For the temperature sensor (P/N 134385 Rev C), the following wires must be connected:

Advanced Harness Blue and White Wire – Pin 17 – Connected to Temperature Cable White Wire.

Advanced Harness Black Ground Wire – Pin 16 – Connected to Temperature Cable Blue and Black wires.

 

Input Wiring Examples

Hood Sensor

The input line must be connected to the wiring point at the base of the hood pin switch under the hood of the vehicle. You’ll need to use additional wire to reach from the input under the vehicle dash to the hood area of the vehicle. The hood pin switch should be placed through the vehicle body so it’s connected to ground, and arranged so the pin is depressed when the hood of the vehicle is down.

 

Seat Belt Sensors

The input line must be connected to one wire of the seatbelt sensor and the other wire of the sensor connected to ground. Attach the wired connector to the belt buckle and the free magnetic sensor to the belt. When the seat belt is placed in the buckle and the sensors are within 1 inch of each other, the input will trigger.

 

Door Sensors

The input line must be connected to one wire of the door sensor and the other wire of the sensor connected to ground. Attach the wired connector to the door frame and the free magnetic sensor to the door. When the door is closed and the sensors are within 1 inch of each other, the input will trigger.
