Welcome to the Tesla Openpilot Wiki!

We're just getting started filling this out, so feel free to jump in and help document things that need to be here.

This port is currently focused on the Pre-AP Teslas from 2014 and earlier. The EPAS (Electric Power Assisted Steering) unit on these pre-AP Teslas is capable of steering itself based on electronic commands like the AP1 and 2 Teslas, but since they don't have autopilot there's a kill signal that is sent to disable this feature. Because of this, we have to proxy the CAN-bus messages through the panda which will alter that kill signal and change it to an enable signal. To accomplish this, you have to remove the frunk liner to get at the EPAS unit, and unplug the factory cable and plug in a bypass cable that allows for this proxying. This cabling also allows OpenPilot to send the steering commands to the car.

Here's what you'll need to get OpenPilot working on your pre-AP Tesla

EON Dashcam DevKit

Panda or Grey Panda

10 foot mini USB cable (this is just an example)

Tesla Giraffe and Wiring harness which are currently only available from Kalud and zax123 in the #tesla channel

Instructions to set it all up

(this is very much in progress and not yet complete)

Flip your EON

Make sure your Eon is up to date (NEOS version, flipped, etc.). If you have problems they aren't Tesla related, check the other wiki / slack places.

Install custom tesla branch of OpenPilot on your EON

Update your Panda (perhaps) - automated soon - Do we need to do this without data on bus?

Remove your frunk liner

Install the wiring harness to the EPAS unit and the OBDII port in the driver footwell

Mount your EON on your windshield

Install Panda on Giraffe ODB2 port (driver footwell)

Run the 10 foot USB cable from the EON along your headliner, down the driver side A-Pillar, and down to the Panda
