Add FSD to a Ram 1500? Here's what works
Tesla's FSD stays on Teslas. But your 1500 can steer itself and follow traffic with one device plugged in behind the mirror.
Yes. Your 1500 is on comma's list.
comma lists the 2019–2024 1500. It needs Adaptive Cruise Control (ACC) on the car. The car's own adaptive cruise keeps speed control. Steering help starts above 32 mph.
Towing and long drives in your 1500
Yes, comma works while towing with the right setup. It’s an amazing upgrade for long highway drives.
Stay especially vigilant and ready to steer or brake. You remain responsible for your truck and trailer.
Match your truck’s year, equipment and software before buying. Confirm your trailer setup with the software project and follow your vehicle’s towing instructions.
Steers itself in the lane
Continuous centring on highways and most roads, not a nudge back from the line.
Follows the car ahead
Your car's adaptive cruise keeps doing the gas and brakes while openpilot steers.
You stay in charge
A driver camera checks your eyes. No city turns, no naps, no FSD claims.
Every 1500 comma lists
Open your year for the exact trim, harness, and what controls speed.
How to add it to your 1500
Four steps. No wiring cut, no dealer visit.
- 1
Confirm your year and trim
Open your exact 1500 below. Trim names decide whether the car has the cruise and camera openpilot needs.
- 2
Order the comma four with the Ram connector
Pick your car in comma's shop and the right harness is added. Nothing else is required.
- 3
Mount it behind the mirror
Stick the mount high and centred, plug the harness in at the camera, and route one cable. About fifteen minutes.
- 4
Drive a few minutes, then engage
It calibrates on your first drive. Then press your cruise button and the 1500 takes the lane.
What the first drive is like
Active Driving Assist versus openpilot
Hands-free Ram driving is a paid package on mapped highways. openpilot gives the Ram 1500 supervised lane centring on most roads.
Questions 1500 owners ask
Do I keep Active Driving Assist?
Yes. The harness sits between the car and its camera, and your factory safety features keep working. Unplug it and the car is stock again.
Does it handle stop-and-go traffic?
Yes on the listed 1500 years. It slows to a stop behind traffic and moves off again on its own.
Is there a subscription?
No. The device and the software are a one-time purchase. comma prime is an optional extra for remote access and longer drive storage.
Do I need to keep my hands on the wheel?
Not constantly. A small camera watches that your eyes stay on the road, and openpilot warns you and stops steering if they do not.
