Installing the Pedal Interceptor

Gen1 Bolt Pedal Firmware

If you have a Gen1 Bolt (2017-2021) and you bought your pedal before June 2025, you will need to flash the firmware of your pedal with a DFU key for proper functionality. See the Pedal Firmware Flashing guide for more info.

To install the Pedal Interceptor, you will need to run a Cat5e (or Cat6) cable from the harness box down to the drivers side footwell. Here, the Pedal will be inserted in series with your accelerator, and connect up to the Comma via the Cat5e cable. You should not need to remove any panels for install. A flat cable is recommended for easier hiding.

Steps:

Route The Cable

1. Plug the Cat5e cable into the harness box behind the mirror (or, at the very least, ensure you have enough length to do so). Make sure you leave just enough slack for the cable to make its way out of the cover once that is reinstalled.
2. Route the cable towards the drivers door along the top of the windshield. You should be able to tuck it up under the trim with your fingers or a rubber pry tool.
3. At the A pillar, route the cable into the trim. The side curtain airbag is inside the A pillar trim, and it is best to try to feed the cable up over the top of the airbag, as to avoid interfering with its operation.
4. At the other side of this trim, you can tuck the cable inside the black door gasket, all the way down to the floor, or bottom of the dashboard.
5. Route the cable along behind the pedals, or attach up behind the dashboard. It is important to ensure the pedals are unobstructed and the cable will not interfere with the operation of your car! Alternatively, if you have weathertech or similar rubber floor mats, you can route the cable under the mats. It's probably less advisable to route under the carpet mats, as they don't cover up as high and may allow the cable to tangle with the pedals.

Install the Pedal

1. The accelerator has a single cable connected to it. This cable has a red tab that must be pulled back. Then, you can squeeze the connecter to unlatch it, and pull it off.
2. Connect this cable to the pedal, and push back in the red tab.
3. Connect the pedal to the accelerator, and push that red tab back in as well.
4. On most bolts, there is a plastic piece next to the accelerator - the pedal can be tucked up inside this area safely, and this will keep it well out of the way of the accelerator. Alternatively, use a strong adhesive or similar to secure the pedal somewhere safe, where it will not interfere with your pedals.

Warning

It is essential that none of the cable routing or the pedal itself interfere with the normal operation of your brake and accelerator pedals. Ensure that there is no way for these items to tangle, jam, or otherwise block your pedals.

Button things up

You can now re-attach the cover behind the mirror, ensuring no cables get pinched or caught, and replace the small plastic peice at the front. There should be enough space remaining for the USB C for the comma & the ethernet for the pedal to come out.
