Why does the the "Harness Assessment Cheat Sheet" say not to connect to the OBDII port for Ford F650+?

Applies To

  • GO device
  • Ford F650 +

Answer

Ford F650+ have both a 16-pin OBDII port along with a 9-pin Deutsch connector. These models provide limited data from the OBDII port (16-pin), which is why we recommend only connecting to the Deutsch connector using a 9-pin harness (recommended: HRN-GS09K2).

The OBD connector only provides access to the GEM module, excluding VIN and odometer. The Deutsch connector (9-pin) provides access to the powertrain and braking system.
