Best Eld For Light Duty Trucks: Compare Cable Types

#1 · Best Overall

1. Pacific Track PT40

• Warranty Description: 1 year

Best for: Light-duty OBDII pickup setup.

Why it ranks #1: Includes a light-duty pickup truck OBDII straight cable and is described as plug-in ready, making its stated fit especially direct for this search.

The included straight cable for light-duty pickup OBDII ports gives this PT40 a direct connection option for compatible trucks. Its pre-programmed, plug-in setup can simplify installation, while the HOS logbook device can also be used for GPS tracking with a compatible smartphone.

The dedicated light-duty pickup cable is the key fit detail: it connects through an OBDII port, rather than requiring a separate cable purchase for that connection. The pre-programmed device and plug-in installation can reduce setup steps for drivers who want an HOS logbook device in a compatible pickup. GPS tracking is also listed, and smartphone compatibility supports a mobile-device workflow. The supplied information does not specify which HOS app is included.

Skip it if you need a listed tablet connection; Garmin eLog supports 9-pin J1939 and 6-pin J1708 ports instead.

Pickup drivers seeking an HOS device with a light-duty OBDII cable and plug-in setup are the clearest fit. The listed connection is for compatible OBDII vehicles, and smartphone compatibility is specified for the workflow.

#2 · Best 16-Pin Fit

2. Pacific Track PT30 16-Pin

• Warranty Description: 2

Best for: Light-duty 16-pin OBDII.

Why it ranks #2: Bundles the PT30 with a dedicated 16-pin light/medium-duty OBDII cable and describes plug-and-play installation for vehicles with OBDII ports.

The included 16-pin light/medium-duty OBDII cable gives this PT30 a specific connection path for compatible trucks and vehicles. Plug-and-play installation avoids wiring and tools, while Bluetooth pairing links the device with a smartphone or tablet for app setup and HOS tracking.

The cable’s standard 16-pin connector is intended for vehicles equipped with OBDII diagnostic ports, making port compatibility central to this bundle’s fit. Connecting the cable to the device and vehicle requires no tools or professional installer, according to the listing. HOS tracking is handled through app setup, and Bluetooth pairs the PT30 with a smartphone or tablet. This setup can suit drivers who want the vehicle connection and mobile logging workflow together, rather than a cable-only purchase.

Skip it if you have a truck needing a 9-pin connector; the PT30 with Green 9 Pin Cable provides that connection.

This bundle suits light- or medium-duty vehicle operators with a 16-pin OBDII port who want a tool-free connection and app-based HOS workflow. It is not the listed 9-pin cable option for other truck ports.

#3 · Best App Flexibility

3. Pacific Track PT30 Square OBDII

• Warranty Description: 1 year

Best for: Light-duty square OBDII bundle.

Why it ranks #3: Includes a black square light-duty OBDII cable, and its listing says it works with compatible ELD/HOS apps on Bluetooth phones or tablets.

The included black square light-duty OBDII cable makes this PT30 bundle a direct option for compatible light-duty trucks. Bluetooth connects the device to a phone or tablet, and compatibility with ELD/HOS apps supports a mobile logging workflow alongside engine-diagnostic data reading.

The black square light-duty OBDII cable specifies the connection included in the bundle, making it relevant to vehicles with a matching diagnostic port. The PT30 reads engine diagnostics data and works with compatible ELD/HOS apps, while Bluetooth supports use with a phone or tablet. The listing also says it can be plugged in or unplugged as needed and offers customizable behavior to match customer requirements. App compatibility and vehicle-port fit remain key parts of the setup.

Skip it if you need a green 9-pin cable; the PT30 bundle with Green Cable – Molex to 9-pin Green includes that connection.

This bundle suits light-duty truck operators whose vehicle has a matching OBDII port and who use a compatible ELD/HOS app. The included cable is the square OBDII type, not the green 9-pin version.

#4 · Best Dual Connector

4. IOSiX Micro ELD OBDII

• Warranty Description: 1 year

Best for: Older trucks with wireless options.

Why it ranks #4: Combines a light-duty OBDII square cable with a built-in 9-pin green connector, giving buyers two stated connection types to consider.

A built-in high-gain, multi-constellation GNSS receiver gives this IOSiX Micro ELD a specified location-tracking component, alongside Wi-Fi and Bluetooth. Its package also lists a built-in 9-pin connector and a light-duty OBDII square cable for supported truck connections.

The built-in 9-pin green connector and included light-duty OBDII square cable offer two connection paths for compatible vehicles, a useful combination when a fleet includes different truck types. Bluetooth 4.2 and Wi-Fi support wireless communication, including simultaneous access-point and station modes. A multi-constellation GNSS receiver with a high-gain antenna supports location data, while a full-color RGB LED indicates status. The listing describes the IOSiX Micro ELD as handling known vehicle-specification deviations in the field.

Skip it if you need a smartphone listed as compatible; Garmin eLog stores records on a compatible smartphone.

Operators of older trucks who need the listed connector options, wireless communication, and GNSS hardware may consider this IOSiX device. The supplied compatibility information names a tablet, so account for that mobile-device requirement.

#5

5. IOSiX Micro ELD Bundle

• Warranty Description: 1 year

Best for: Mixed-connector truck fleets.

Why it ranks #5: Pairs a light-duty OBDII square cable with a built-in 9-pin connector and describes support for older and newer vehicle variations.

A built-in 9-pin J1939 Type II connector paired with an included light-duty OBDII square cable gives this IOSiX-based ELD two connection paths. Its auto-detection and auto-bauding can help it handle supported vehicle protocols, while Bluetooth and Wi-Fi provide wireless communication options.

The built-in 9-pin connector supports new and legacy vehicles, while the included light-duty OBDII square cable extends the package to compatible light-duty trucks. Physical-layer and protocol auto-detection with auto-bauding can simplify connecting across supported configurations. Bluetooth 4.2 Class 1 and Wi-Fi with simultaneous access-point and station modes add wireless communication choices. The listing identifies a tablet as a compatible device, so buyers should account for that stated mobile workflow.

Skip it if you need a smartphone listed as compatible; Garmin eLog stores records on a compatible smartphone.

Fleet operators with supported 9-pin or light-duty OBDII connections can make use of the included connector options and protocol detection. The supplied compatibility details name a tablet, so check that this matches your intended device workflow.

#6

6. Pacific Track PT30 9-Pin

• Warranty Description: 1 year

Best for: Offline-capable 9-pin logging.

Why it ranks #6: Includes a green 9-pin round cable and lists J1939, J1708/J1587, and OBD-II connections, though the included cable is not identified as light-duty.

Large-capacity storage for offline operations sets this PT30 apart for drivers who need data retained when connectivity is unavailable. The included green 9-pin round cable, Bluetooth Low Energy interface, and compatibility with ELD/HOS apps provide a mobile logging setup for supported vehicles.

The green 9-pin round cable connects the PT30 to compatible vehicle ports, while Bluetooth Low Energy communicates with a phone or tablet running a compatible ELD/HOS app. Large-capacity storage supports offline operations, and integrated engine diagnostics can provide vehicle diagnostic data to the workflow. The device can be plugged in or unplugged as needed, according to the listing. Its stated connections also include J1939, J1708/J1587, and OBD-II, though the supplied bundle specifies the green 9-pin cable.

Skip it if you need a light-duty square OBDII cable included; the PT30 bundle with Black Square Light Duty OBDII Cable includes one.

Drivers seeking offline storage, engine diagnostics, and Bluetooth app communication may value this PT30 bundle. The included cable is green and round with a 9-pin connection, so verify that port matches the vehicle.

#7

7. Pacific Track PT30 Green Cable

• Warranty Description: 1 YEAR

Best for: Multi-protocol 9-pin bundle.

Why it ranks #7: The bundle includes a Molex-to-9-pin green cable and lists J1939, J1708/J1587, and OBD-II connections, but lacks a specifically light-duty cable.

The included green Molex-to-9-pin cable gives this PT30 a defined connection for compatible trucks, while the device lists J1939, J1708/J1587, and OBD-II connections. Bluetooth app support and engine-diagnostic reading add a mobile logging and vehicle-data workflow.

The green Molex-to-9-pin cable is the supplied connection, so it is the practical starting point for checking vehicle fit. The listed J1939, J1708/J1587, and OBD-II connections indicate broader protocol support, while the device reads engine diagnostics data. Bluetooth links the PT30 with a phone or tablet running a compatible ELD/HOS app, and customizable behavior can match customer requirements. The listing also says the unit can be plugged in or unplugged as needed.

Skip it if you need a light-duty square OBDII cable included; the PT30 bundle with Black Square Light Duty OBDII Cable is the listed option.

Drivers with a compatible green 9-pin connection who want engine diagnostics and Bluetooth app use may find this PT30 bundle relevant. Its supplied cable is Molex-to-9-pin, so it is not the square light-duty OBDII bundle.

#8

8. Konexial My20 ELD

Best for: App-based fleet telematics.

Why it ranks #8: Lists OBD-II diagnostic-port support through an adapter available separately, but requires a subscription and the standard connector is 9-pin J1939.

Konexial’s My20 combines ELD logging with GPS tracking, log auditing, DVIR, digital documentation, fuel information, messaging, reports, and maps. Bluetooth links the diagnostic-port device to an app on a compatible phone or tablet, bringing those listed fleet tools into a mobile workflow.

The standard 9-pin J1939 connector supports a direct diagnostic-port installation, followed by app setup and Bluetooth pairing with a smartphone or tablet. For vehicles with OBD-II or 6-pin ECM ports, adapters are available for purchase, giving buyers a route to those connections. The listed My20 tools include GPS tracking, log auditing, DVIR, documentation, fuel information, messaging, reports, and maps. The service requires a subscription that must remain current for compliance.

Skip it if you want a no-subscription ELD; Garmin eLog records HOS without subscription fees.

My20 fits drivers and fleets wanting ELD functions alongside listed telematics and documentation tools in a phone-or-tablet app. Its service requires an active subscription, and non-9-pin ports need separately purchased adapters.

#9

9. Pacific Track PT30 9-Pin Cable

• Warranty Description: 6 Month

Best for: Commercial-vehicle 9-pin connection.

Why it ranks #9: Includes a 9-pin cable and Bluetooth connectivity, but its description calls it ideal for semi trucks rather than specifying a light-duty OBDII fit.

A supplied 9-pin cable gives this PT30 a direct diagnostic connection for compatible trucks and commercial vehicles. Bluetooth communication with compatible mobile devices and ELD applications supports a connected logging workflow, while the listing also describes vehicle-data access for compatible ELD software.

The included 9-pin cable is the defining fit consideration, connecting the device to compatible commercial vehicles through that port. Bluetooth lets it communicate with compatible mobile devices and ELD applications, so the logging workflow depends on supported software rather than a screen-based interface. The listing says it connects to vehicle data for compatible ELD software and describes location tracking for fleet operations. Buyers should match the cable connection and software compatibility to their vehicle and workflow.

Skip it if you need a light-duty OBDII cable in the box; the PT30 bundle with 16-pin OBDII cable includes one.

Commercial-vehicle operators with a compatible 9-pin port and ELD application can use this PT30 for a Bluetooth-connected workflow. Its included cable is 9-pin, so it does not match the listed light-duty OBDII bundle.

#10

10. Garmin eLog

• Warranty Description: 1 year limited warranty

Best for: J1939 or J1708 logging.

Why it ranks #10: Supports 9-pin J1939 and 6-pin J1708 ports but explicitly excludes OBD-II protocol, making it a poor match for many light-duty trucks.

Support for both 9-pin J1939 and 6-pin J1708 diagnostic ports gives Garmin eLog a clear fit for trucks using either connection. It records Hours of Service, stores records on a compatible smartphone, and avoids subscription fees through its one-time-purchase model.

The two supported diagnostic-port standards—9-pin J1939 and 6-pin J1708—give this ELD connection options across compatible trucks. HOS records are stored securely on a compatible smartphone and can be accessed for inspection through the device’s USB port or FMCSA web services. Its one-time-purchase, no-subscription model keeps the listed service arrangement straightforward. It is not compatible with OBD-II protocol vehicles, and Volvo-engine vehicles with 16-pin J1962 require a separate cable.

Skip it if you use an OBD-II truck; the PT40 includes a light-duty pickup OBDII cable for compatible vehicles.

Garmin eLog suits operators with J1939 or J1708 ports who want smartphone-stored HOS records and no subscription. It is not the fit for OBD-II protocol vehicles, and some Volvo 16-pin setups need a separate cable.
