Model 3 OBD2 Harness

[VHarl]

Selling harness compatible with Model 3 (not 100% sure if it will fit the recently 2021 refreshed Model 3, but definitely NOT compatible with Model Y!)

OBD2 port allows to read CANBUS data that is otherwise not available from main screen.

Plus on the bottom of/behind the rear vent.

$30 shipped

I can't remember where I purchased mine from now, but I did purchase the late model cable for my 2020 Model Y. Yes, there's very little room to put the plastic back on, but I was able to get it to work. I keep the OBD out stuck under the right side of the console between the passenger seat. I would recommend verifying the year of your model 3. They changed the plug type around 2019 and may be the reason not compatible with the Y.

What yr model 3's does this work on? I'll take it if it fits a 2018.

Yes, I had it installed in a 2018 M3, so definitely compatible.
