Model Y Tow Plug Adapter

[BrianT]

Apologies if this is discussed already, but I cannot find it.

Regarding the tow electric plug:

Q: is the Tesla end the same as "7-way RV style" I've seen?

Q: would this one be a good choice for 4 or 5 pin use?

Q: This 4 pin has lights, which looks attractive for verifying function.

Q:Which would you pick of the above 2 (assuming they both will work)? ... or something else?


Thanks much!

I tried the first one it didn’t work so I return it and got the Curt led convert adapter I heard lots issues with led lights on trailer and won’t come on. It’s coming in tomorrow I will let you know if it works.

Hello, checking back on this to see if the last adapter worked for you?

Nope I try plugging it in and still nothing. I think they turn off the plug no power at all going though the hitch cables they install.

This is what I'm using, though mine had red wire instead of the pictured black.

Tesla is considered a "round connector". You'll want an adaptor to a 4 flat or 5 flat. I think that I got mine off of Amazon, but it may have been a Walmart store. I actually got a round to 4 and 5 flat.

The difference between a 4 and 5 flat is that the 5 adds brakes. My trailer has brakes, so I need a flat 5.

And you need to make sure that the car lights are on before you test the trailer's.

Yeah been testing it every different way and nothing. But if I plug it into my Subaru test works.

if you stick your hand in the cavity, do you find an unconnected connector?

see the thread i started before finding this:

Trailer wiring and a dangling connector

I have a fairly early 2021 model y with factory installed tow package. I’ve only ever utilized the tow package for a bike carrier - thus never plugged in to the trailer electrical connector. Recently I bought some lights to put on the back of the bike rack to try to mitigate any brake light...

Note that it can be a pain to remove due to the Tesla plastic cover but it's not a big deal.

 

[Wu01ok]

Yeah I have something similar but still doesn’t work I think the wires aren’t connected.

I would recommend this hitch cover works great.

Finally took my car for service so they had it for 2 days and found the issue why my hitch wires weren’t working. They were install wrong lol.
