Red plug?

[Dave in Utah]

There's a red plug in the compartment under the passenger seat, right hand side, clipped into the plastic above the tail light connector. It's part of the tail light wiring harness, but it doesn't go anywhere. Anyone have any idea what it's for?

I believe that is the engine diagnostic connector. Of course I have never used it.

this is for a NT1100

My electronic guru sez it is a diagnostic connector, however I would take that with a grain of salt until we can get human confirmation.

Thanks; yes, 2025 NT1100DCT. Diagnostic port makes perfect sense.
