Select Cable for ELD Follow

Follow these steps to identify and select the appropriate cable for your vehicle's ELD device:

1. Locate your vehicle’s diagnostic port. Common locations include under the dash, beside the steering wheel, near the driver’s left kick panel or beneath the driver’s seat.

2. Identify the diagnostic port type. 

Diagnostic port types vary based on the vehicle’s make, model, and year.

For heavy-duty vehicles, as a general rule of thumb:

• Vehicles built between 1996-2001 typically use a 6-pin diagnostic port.
• Vehicles from 2002-2006 may have either a 9-pin or 6-pin port.
• Vehicles manufactured in 2007 or later generally have a 9-pin diagnostic port.
• Mack or Volvo trucks manufactured in 2013 or later use a specifically designed 16-pin cable. Do not use 9-pin or 6-pin cables.

Light and medium-duty vehicles such as pick-up trucks usually require a 16-pin (OBD2) cable.
