New XP yoke, self install?

[Jimmyduc]

I think I can buy upgraded oem (central horn) yoke off of Ebay, for 600 or so. The install looks straight forward, but does anyone know if a firmware update would be required. Or should it be plug and play. My current yoke is fine other than I very much dislike the horn button. Not sure if Tesla mobile would install self bought yoke. Wonder what Tesla charges for the new yoke if not a waranty claim?

Does require a gateway config update. You can do that with toolbox. Depending on the build date of your car, you may need a Ethernet media converter to connect to your computer

Is this update strictly for the AP/FSD icon (switch from round to yoke icon) or does it provide more functionality? I’m switching from a round wheel to yoke and purchased the latest yoke with central horn on eBay.

Need the config updated for the horn and camera button to work

I was able to swap to the yoke and airbag (updated with center horn) without issue. However, I had an error pop up that said the buttons would not function properly and I don’t have toolbox to make the changes myself.

Scheduled an appointment with Tesla to have them update the firmware so it recognizes the yoke with the central horn but they are refusing because I did not purchase the yoke/airbag directly from them.

You may as well grab a toolbox subscription and do it then. A day is $160ish. You might also be able to split the subscription with someone. If your car was built prior to ~February 2022, you'll need a media converter to connect.

I’m assuming all I’ll need then is an Ethernet cable? Mine is a late 2023 Model X. Also, I see toolbox 3 lists Windows 10 or 11 but I see recent videos running it on a Mac. Will I be able to use my MacBook Pro or should I pick up a cheap Windows laptop to run it on?

Thank you so much for your help. It’s greatly appreciated.

Not gonna lie OP...with the questions you're asking, spend the extra cheddar and let Tesla install for you. Not sure you can man your way through this one

To make gateway changes you need to be able to use the service shell which requires toolbox proxy. That's a windows only app. You can use wine or windows in a virtual machine to run that... but I'll let you decide what would be easier for you.

In your case you'd need to set configid 114 to 05 and 121 to 03

configid:
114 (cfg_steeringheatertype)
data:
04 (ZF_ROUND)
05 (ZF_YOKE)

configid:
121 (cfg_steeringwheeltype)
data:
00 (ROUND)
01 (YOKE)
02 (YOKE_HORN_IN_DAB) // never used, presumably they were planning on horn within the airbag itself
03 (YOKE_MECHANICAL_HORN)
04 (ROUND_MECHANICAL_HORN)

I was thinking of doing on my own too since it is cheaper to find a set on eBay but I guess gonna wait to see if there is a solution to upgrade on the software side.

You may try ask 3rd party Tesla approved body shop. When I ask SC to update my steering wheel configuration, service manager said they can't do it there. He told me 3rd party Tesla approved body shop has toolbox software can do the update, just don't go to any Tesla owned shop.
