WinCinti Posted June 17, 2021 Share Posted June 17, 2021 96 Monaco Windsor 8.3L Cummins Trying to use BlueFire sensor Found an OBD (not 2) connector. On right side of steering column a 12 pin rectangle on 4 pins connected. Purchased an OBD to OVD2 adapter cable Purchased a OBD2 to green 9pin diagnostic to accept BlueFire sensor. Doesn't work. No blue light on sensor. Any ideas on where to dig in appreciated. 1 Link to comment Share on other sites More sharing options...
Dr4Film Posted June 17, 2021 Share Posted June 17, 2021 (edited) Did BlueFire claim that it would work on your 1996 8.3 Cummins engine? According to their website it only works on heavy duty vehicles with a round 6 or 9 port or light duty OBDII port equipped vehicles.

CMillet86 Posted June 17, 2021 Share Posted June 17, 2021 1996 is still mechanical isn’t it? If that’s the case there’s no engine computer at all. That diag connector is for the Allison most likely. Link to comment Share on other sites More sharing options...
DavidL Posted June 17, 2021 Share Posted June 17, 2021 (edited) OBD2 is for gas vehicles post 1996. That connector looks like obd1 You can find adapters to connect the plugs together, but that does not mean the scan tool can talk to the protocol of your vehicle. Contact bluefire to see if your engine / obd1 is supported. if not, sell it. The protocol is the "language" the vehicle and scan tool communicates with. You can "hear" someone who speaks Latin, but that doesn't mean you can understand what they are saying. The vehicle, the connector, the scan tool, the software all need to be compatible with each other. Edited June 17, 2021 by DavidL Link to comment Share on other sites More sharing options...
Rikadoo Posted June 18, 2021 Share Posted June 18, 2021 I dont know ANYTHING about blufire however if your trying to connect to your OBD2 an nothing is powering up then test your plug 4&5 are ground an & 16 is your power, start checking for power an grounds, cause that is what powers up ALL scan tools.

just_john1 Posted June 18, 2021 Share Posted June 18, 2021 I have the same problem on my 97 Dynasty. From what my research came up with is we are SOL. I haven't checked my engine compartment yet to see if I can locate a plug. If you find the answer please let me know. Thanks. Link to comment Share on other sites More sharing options...
