Model Y Brake Controller

[Webeevdrivers]

Thanks for replies.
No tow package, and correct - I meant white brake controller connector (4 pin) in left (driver) footwell.
Is there any chance to activate it? If not would appreciate any footwell-located tap-in spots for 12v suggestions.

My apologies. I misunderstood. Consider outing in a ticket and asking tesla, or if you are close enough to a service centre ask the shop manager. Please report your findings back.

Good luck.

I'm pretty sure he was talking about the brake controller connector under the dash, not the trailer connector at the back of the vehicle.

Whooos. My bad.

You need the tow package to get power from the harness in the driver footwell.

Thanks for confirming , this makes logical sense.

same thing here, bought the adapter to power my dash cam, but i read somewhere that they recently disabled this port, which used to be a a reliable switched source.

Want to sell your connector?

You can go into a Tesla service center and buy one for around $5.

 

[Ratm68]

yup, not worth the trouble and postage to ship you mine

The Curt Echo has a three-way accelerometer within the chassis of the plug itself, which plugs into the 7-way trailer connector

Does anyone know if this works on 16V cars that don't supply the accessory power at the 7-pin connector?

I don't believe it does. My research indicated that the Echo requires power from the marvelously inoperative aux power pin. I really want to use the that brake controller in order to avoid tapping into a circuit to use a different brake controller.

Has anyone heard anything at all about Tesla finally fixing this?

I filled out a safety reporting form with DOT to let the Feds know that Tesla sells incomplete tow packages that could result in trailers with electric brakes having no emergency braking in the event they come loose from the tow vehicle.

The emergency braking comes from the trailer’s battery. Not the car.

Of course it does.

And the charging for that battery comes from the 12v aux pin on the trailer connector. Which doesn't get charged on lithium battery MY's because Tesla didn't bother to step the voltage down and left the pin unpowered. So the trailer battery, which is needed to power the trailer's emergency brakes, will eventually go dead.

Note: Some trailer emergency brake batteries are dry cells without a charger, others are built with batteries and a small charger and charge via the 12v aux power pin - those are the ones (like mine) that will go dead because they are not getting charged.

Yes. Having said that, where travel trailers are concerned, usually there are solar panels on the roof of the trailer.

Not a thing for utility trailers with brakes though. I suppose that could be an issue.
