2021 Model Y w/ Tow Package, Car side connector won't power, trailer mode indicator is red

[EBMyCH4]

I just sort of inhereited a cool little 6 x 10 trailer. I slapped a new LED light kit on last night, and tried to use the light connector (for the first time with this car) but the car won't power it.

I put a multimeter on it, no juice at all, to any of the blades. Also, there's this weird connector hanging down right above the 7 pin...

Any thoughts on this y'all? Any idea what the weird hangy down thing is?

Your trailer LED lights may have too little resistance to trigger tow mode in your Y. Search the X forums and there are discussions about that issue.

Or I could be wrong and your problem has nothing to do with that. Hard to say from over 1,000 miles away…

When I got my MY with tow package, Tesla forgot to appropriately hook up the tow electronics so my 7 pin was DOA.

I had to make a service appointment to have it resolved. If your trailer requires a brake controller, make sure you get them to give you the pig tail adapter while you’re there. It is supposed to come with the vehicle, but it doesn’t.

Damn - do you know how they connected it? Next service appointment is weeks out.

Update: Tesla service is terrible. The chat function in the website is a runaround. I sent a message through the app and they stonewalled me. I'm on the edge of making a bbb complaint. This is infuriating

Could you post a picture of the pigtail adaptor please

Tesla got me in to a service center today, and the cause was that connector in the photo that i origianlly posted - most likely the same issue as @glide

They needed to pull the whole bumper to connect it. Thanks for weighing in everyone.

If you search the MX forum, someone has pics posted.
