Asset Gateway: Devices and Installation Methods

Motive offers different models of Asset Gateway (AG) devices to help fleets track trailers, heavy equipment, and other valuable assets. Each device supports multiple installation methods depending on your asset type, power source, and cabling configuration. Use this article to identify your device and find the correct installation method and guidance.

Asset Gateway Mini (AG-31)

The Asset Gateway Mini (AG Mini) is Motive's current-generation compact asset tracker for trailers, heavy equipment, and field assets. It supports both battery-powered and cable-powered modes and automatically switches between them as needed.

General installation for Asset Gateway Mini (AG-31) 
Battery-Powered AG Mini installation Installation: Asset Gateway Mini (Battery Powered)
  • Use for assets without an available external power source 
  • No wiring required
  • Installs in under 10 minutes. 
  • Supports check-in rates of 8, 12, 24, or 48 hours (12 hours recommended).

Note: Does not support Environmental Sensor connectivity.

Cable-Powered AG Mini installation  Installation: Asset Gateway Mini (Cable Powered)
  • General cable-powered installation guide covering installation for all cable types (3-wire, 8-wire, ABS) through the Motive Fleet App. 
  • Includes guided GPS/LTE signal testing before mounting and AUX line configuration. 
  • Use this article as the starting point for any cable-powered AG Mini installation or for the in-app guided installation workflow.
Cable-specific installation methods for Asset Gateway Mini (AG-31)
3-Wire Cable for Trailers AG Mini 3-Wire Cable Installation for Trailers
  • Use for commercial trailers, chassis, agricultural trailers, and smaller cargo trailers. 
  • Cable (CABLE-AG-31.2-3WR) connects to the trailer junction box: red wire to power, black wire to ground, green wire (optional) to detect ignition on/off.
  • Best to use when the trailer has a constant power source available at the junction box and real-time 1-minute tracking is required.
3-Wire or 8-Wire Cable for Heavy Equipment AG Mini 3-Wire and 8-Wire Cable Installation for Heavy Equipment
  • Use for skid steers, excavators, mowers, chippers, and agricultural equipment. 
  • The 3-wire cable (CABLE-AG-31.2-3WR) provides power, ground, and ignition detection.
  • The 8-wire cable (CABLE-AG-31.2-8WR) adds two AUX wires for monitoring additional equipment states such as forklift arm position. The additional wires are reserved for future use.
  • Best to use when tracking heavy equipment that moves between sites or when monitoring engine hours or additional equipment functions via AUX lines.
ABS Cable for Trailers and Chassis AG Mini ABS Cable Installation for Trailers and Chassis
  • Use for commercial trailers and chassis with an accessible ABS module. 
  • The ABS cable (CABLE-AG-31.2-YABS) connects in-line with the existing ABS harness with plug-and-play setup and no wire splicing required. 
  • Provides power from the ABS module and surfaces trailer diagnostic data, including light fault codes.

Note: The device is powered only while the trailer is tethered to a running vehicle.

Reefer and integrated unit installation methods for Asset Gateway Mini (AG-31)
Reefer Trailer AG Mini Installation for Reefer Trailers
  • Use for connecting the AG Mini to refrigerated trailers. 
  • Three power source options are covered: Reefer battery, ignition line, and ABS cable.
  • Use of reefer battery as a power source is recommended when continuous monitoring is required even when the reefer is off.
  • Reefer ignition line powers the AG only while the reefer is running. 
  • ABS cable powers the AG only while tethered to a vehicle
  • Required for fleets using Environmental Sensors (ES-2) or Door and Environmental Sensors (DES-2) on reefer trailers. Sensors require cable-powered mode on an AG-31.3 or later device.

Asset Gateway Solar (AG-55)

The Asset Gateway Solar (previously referred to as Asset Gateway Max) is Motive's first-generation asset tracking device. It features a gray enclosure with a built-in solar panel for passive charging. 

The AG-55 supports cable power via Cable 4020 and integrates with Thermo King reefer units. It captures GPS and telematics data but does not provide CAN bus error codes or vehicle diagnostics, which require a Vehicle Gateway. 

Asset Gateway Solar is identified by the model number AG-55. There are no further sub-versions for this model. 

Note: The Asset Gateway Solar (AG-55) devices have been discontinued. No remaining inventory is available for purchase. Existing devices in the field are still supported. For new deployments, Motive recommends the Asset Gateway Mini (AG-31).

Installation type Guide link When to use
General installation for Asset Gateway Solar (AG-55) 
Asset Gateway Solar general installation  Installation: Asset Gateway Solar
  • General solar-powered installation guide covering mount plate installation and optimal mounting locations on dry vans, flatbeds, reefers, and tankers.
  • Use this as the starting point for any AG Solar installation. 
Cable-Specific installation methods for Asset Gateway Solar (AG-55)
Cable 4020 for Trailers Installation: Asset Gateway Solar with Cable-4020
  • Use when connecting the AG Solar to a trailer's 7-way (J560) connector to provide constant external power via Cable 4020. 
  • Recommended for reefers and any mounting location that receives limited sunlight.
  • Best to use when the trailer has a 7-way connector and consistent cable power is needed to supplement or replace solar charging.
Cable 4020 — Wiring Guide Cable 4020
  • Standalone wiring reference for Cable 4020, covering power source identification, ground connection, fuse installation, and drip loop best practices for 12–24V vehicle power.

Note: Applies to both AG Solar and Vehicle Gateway installations.

Reefer and integrated unit installation for Asset Gateway Solar (AG-55)
Thermo King Reefer Integration Installation: Solar Thermo King Integration
  • Use for connecting the AG Solar to a Thermo King refrigeration unit using Cable 4000 and the Cable 4001 adapter with the Thermo King 3rd-party harness. 
  • Covers pre-installation setup for both BlueBox (P/N 401634) and iBox (P/N 401243) units, including enabling 3rd Party Mode and Guarded Access configuration on the Thermo King controller.

Note: ES-2 sensors in the field have older firmware compatible only with the AG Solar. If migrating to an AG Mini (AG-31.3+) or Vehicle Gateway 3, ES-2 sensors with updated firmware are required.
