GM Vehicles

What do you need for GM vehicles

Vehicles require Pedal

** Pedal firmware for Bolt vehicles is still updating regularly. DFU key is highly recommended for a bolt pedal.

What is needed:

1. Pedal

2. Harness & Harness box (To connect the pedal, you will need a harness box with rj45 port)

GM:

• Chevy Bolt EV with and without ACC (before 2022)

• Chevy Bolt EV without ACC after 2022

• Chevy Bolt EUV with and without ACC (before 2022)

• Chevy Bolt EUV without ACC after 2022

• Chevy Volt without ACC

How to identify which version of harness box is needed:

1. If you have a harness box with rj45 port - you DO NOT need another harness box to use pedal

2. If have a harness box purchased from Comma, with no rj45 port - you will need a 2x9 pin box

3. If you plan to purchase the harness + box (GM only) from me, then it is 2x13 pin box

4. If you purchased a used harness with no box, please DM me the picture of your harness. (the old ones before 2024 June are 2x13 pin)

5. If you purchased a customized harness for Tesla, you will need a 2x13 pin box

What else do you need:

• An ethernet cable

  • For smaller cars, 11ft in length or more

  • Please avoid flat noodle cable
