Common Questions
Which port does my truck have?
Most trucks from 2005 and older use the 6-pin port, and most 2006-2015 trucks use the 9-pin. The port guide above lists each make by year.
Where is the diagnostic port?
Usually under the steering wheel on the left side.
Do 2014 and newer Volvo or Mack trucks need this cable?
No. Those use the standard 16-pin OBD2 port, so our modules plug in directly.
What does it connect to?
It connects our OBD2 performance modules to your truck's 6-pin J1708 or 9-pin J1939 diagnostic port.
