I have created a turn signal lever for retrofitting my Tesla Model X.
Only 2 screws (M5*16) and 2 nuts are required. Everything else can be printed.
The electronic components required are the SEXY buttons from ENHANCE. You can order them here https://enhauto.com/.
On the right side I have the turn signal function. On the left side I can activate and deactivate the Plaid mode and 0% recuperation.
I have only tested with the Tesla Model X (built from 2022). It is possible that this retrofit kit also fits the Tesla Model S.
If any of you test it with the Model S, please write in the comments.
I offer this retrofit kit for free and am not liable for anything.
You can see the assembly here:
Have fun with it.
