9 pin round to use a Bluetooth transmitter
I was thinking of this too. Adding an oil temp gauge and an EGT gauge.
What tool is that? I use the Blue Driver for my scan tool on other vehicles (havent put it on the tractor yet) but I like how that one is laid out.
Most ag tractors I've seen use the 9 pin round. Maybe New Holland wanted the round on their models so they are standard across the models.Interesting... I thought that standard 16 pin obdii connectors were required in the USA
I wonder if tractors are exempt?
Would be an interesting question for New Holland dealers.

George do you mind sharing which adapter and elm327 that you bought.Not sure if it's the same but on mine you have to remove the right side panel under the ignition key. Mine is a round 9 pin receptacle (CAT style plug). Had to buy an adapter plug that converts it to standard OBD II. Then plug in the ELM 327 and used an Android phone with torque pro or similar program.
