What do you need for GM vehicles
Vehicles require Pedal and GM harness set
** Pedal firmware for Bolt vehicles is still updating regularly. DFU key is highly recommended for a bolt pedal.

How to identify which version of harness box is needed:
If you have a harness box with rj45 port - you DO NOT need another harness box to use pedal
If have a harness box purchased from Comma, with no rj45 port - you will need a 2x9 pin box
If you plan to purchase the harness + box (GM only) from me, then it is 2x13 pin box
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)
If you purchased a customized harness for Tesla, you will need a 2x13 pin box
