Disconnected plugs under dash

[Obi-Wan-YJ]

I have a 2016 XR4145. This week, I pulled off the kick panels below the dash and noticed that on the right side, there are two matching plugs that are disconnected. What are they for? Should they be reconnected?

On a related note, I heard that there was a diagnostic plug under here somewhere. I was hoping it was OBDII-compatible. Anybody know where I could find that?

Try asking the prior owner about the plugs. If everything works they may be for an optional accessory. As far as OBD II is concerned a tractor's connector may fit an automobile's reader but to not expect the codes to mean the same things.

There is an OBD diagnostic connector but the center panel may have to be removed to get to it. The OBD connector can be unplugged from the harness so that the dealer can hook up their service tool laptop directly to the harness without taking off the center panel to access the connector. It's kind of a shortcut. It appears the connectors in your pictures are of the OBD connector unplugged. The dealer probably used the shortcut and didn't plug it back in, which makes no difference unless you remove the center panel and try to use the OBD port. It could be plugged back in, but an automotive code reader used on the OBD port will not be able to read tractor fault codes because they are different. Codes can be read on the instrument cluster and use a fault code list to see what they mean. I have a list printed out for my use, and someone has a list posted in this forum somewhere but unfortunately, I don't remember where I saw it. Someone else may be able to help with that.
