16-PIN Adapter for Volvo/Mack


16-PIN adapter for 2013 or newer heavy-duty Volvo or Mack truck.

It attaches to the vehicle’s diagnostic port. The diagnostic port is generally located in one of four places:

  1. Underneath the left side of the dash
  2. Underneath the steering wheel
  3. Near the driver’s left kick panel
  4. Below the driver’s seat




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

Most vehicles manufactured in 2007 or later will have the 9-pin diagnostic port
Vehicles manufactured from 2002-2006 may have either the 9-pin or 6-pin diagnostic ports
Vehicles built from 1996-2001 generally have the 6-pin diagnostic port

If you have a model year 2013 or newer Mack or Volvo truck, you should not order a 9-pin or 6-pin cable. You should order the cables specifically designed for model year 2013 or newer Mack or Volvo trucks.
