9-Pin to 6-Pin J1708 Bluetooth Adapter

Our 6-Pin standalone adapters are no longer available. Instead you need to order a 9-Pin adapter along with a 9-Pin to 6-Pin converter cable or connector.

Our 9-Pin Adapter plugs into the 9-Pin to 6-Pin connector which in turn connects to the 6-Pin diagnostic port of any Class A Motorhome or Class 3 through 8 heavy duty truck. The Adapter is constructed of industrial grade materials, will withstand abuse, and is weather resistant.

Important Note - The BlueFire App defaults to connecting to a J1939 data bus. You must change this in Settings to 'Connect to a J1708 Data Bus'.


You first need to order one of our Adapters below:

9-Pin J1939/J1708 Bluetooth Android/Windows Adapter (Not for Apple).

9-Pin J1939/J1708 Green Bluetooth Apple/Android/Windows Adapter.


And then, with a separate vendor order, one of the connectors below:

9-Pin to 6-Pin Connector.
