How to permanently disable Auto Start-Stop on Ford F-150 – easy method

All Ford F-150 13th gen vehicles come standard with Auto Start-Stop feature which offers little benefit but is of great annoyance and potentially harmful to your vehicle’s battery and starter in the long run. This guide will help you permanently disable this feature on Ford F-150 without spending a dime.

So you’re tired of pressing that Auto Start-Stop button on the dashboard every time you hop in your truck? Worry no more! With this quick and easy fix, you will never have to press that button again, ever!


  1. While your vehicle is turned off, look under the steering wheel and find a white box at the top left corner with 3 connectors connected to it.
  2. Disconnect the lowest connector which is for Auto Start-Stop button.
  3. This will automatically put the system in bypass mode – disabling the Auto Start-Stop function.

Note: Your dealership may not like unplugged wires and make a fuss about it – so make sure to reconnect this wire when you go back for vehicle service.

Important Safety Update: It has been pointed out in the comments section that you will need to connect the plug back in when towing a trailer, otherwise the lights will not work on the trailer.

Warning! Do not use trailer line tester to bypass Auto-Start Stop. A lot of websites and videos on Youtube have been recommending permanently plugging in trailer line tester at the back of your truck to bypass this feature. We do not recommended this method as it can be dangerous. You insert the trailer plug and the computer goes into tow mode. Shift points change, fuel economy drops a bit, trailer sway control is enabled dropping the MPG a bit more. Backup camera does not function. Rear proximity sensors are disabled. It also disables other safety features like rear cross traffic detection. So if you’re already using this method, we recommend that you unplug it right now.

Another video that I watched said to make sure that you plug the one you disconnected back in if your going to tow a trailer, otherwise your trailer lights won’t work.

Totally, I tried renting a U-Haul and the lights didn’t come on. I totally forgot and ford charged me 100 buck to plug it back in.

Thanks for this great fix. In addition to simply disliking the feel of this feature I’ve read that at least some motors are experiencing premature wear of the timing chain sprockets due to the excessive starting. Unfortunately, for owners – it happens after the warranty is over. Similar thing happened with Honda’s VCM system which shuts down cylinders to save fuel – but has led to thousands of cylinder failures costing about $2,000 to repair. So much for saving money!

Thanks for the tip. Works like charm. Easy enough to hook back up when needed.

Engineering Explained did a video on this in depth. Long story short, it saves more fuel than idling after about 7 seconds in most cases. As far as wear and tear on the ignition system, these engines are designed with the auto stop function in mind. However, it does add more wear and tear regardless. In my vehicle it doesn’t bother me because I’ve become used to disabling it if I need to, otherwise it does its thing. I don’t quite understand why it bothers so many people, so if you or anyone else can explain the problem with facts and not resort to personal opinions (since personal opinions are what I’ve mostly heard from those opposed to it) I’d like to hear it.

My concerns are with response and powertrain wear. Try coming up to stopping then throw it in reverse and make a backup turn like any other normal vehicle. If you time it like a vehicle without auto start stop take a listen to that trans shift to reverse and listen to the rear end gear noise. Cant be good. I feel a lot of powertrain jarring after the starter restarts truck that surely cant be good on mounts at a minimum, or heavily or critically wearing engine/trans/rear end at a maximum. Id be referring to a 2018 Sport SE 4×4 SuperCrew with 5.0 V8 operating in 2 wheel rear drive mode. That said, Not sure I’ve enough courage to keep auto start stop enabled when 4 wheel drive is on.

My dislike of this feature stems from two instances where the autostart had kicked in as I was waiting in a turn lane. As accelerated to cross, the engine started and truck was moving but my power steering was not adequately ‘powered up’ and I nearly hit a pole on the corner. I HATE this option. The effort to save a few dollars in gas does NOT justify the safety concerns.

KC, the same has happened to me several times. The Ford Techs say it is impossible. It is a true safety issue in my opinion.

Because in Phoenix there are less than three weeks a year when I don’t mind the air conditioning being reduced or turned off at a stop light.
