Description
Does NOT affect your vehicle’s electrical system. The same effect would be if you manually pulled out your Starter Relay (or Fuel Pump Relay); effectively breaks the electrical pathway to your Starter motor.
SEE: INSTALLATION INSTRUCTIONS
HOW IT WORKS:
- Our custom Relay Bypass Module replaces your vehicle’s factory Starter Relay (or optionally your Fuel Pump Relay).
- Hide the wired included Toggle Switch (or use your own toggle/pushbutton) OR the Wireless Remote Switch somewhere in your vehicle only you know. With the Kill Switch activated, your vehicle will not start.
- That’s it!
What is included in the kit:
- Control Junction Box
- Relay bypass module
- Pushbutton Switch in Wired Version (OR) Two Wireless Remotes in Wireless Version
- Wiring Harness
- Wire Connectors
Q & A
Does this void my vehicle’s warranty?
No. There is no cutting or splicing of your factory vehicle’s wiring whatsoever. It is completely reversible, just remove the Relay Module and pop back in your factory relay module and it’s back to factory stock.
How difficult is the installations?
The Wired Version is a Level 2-3 out of 5 difficulty mostly due to having to run the Pushbutton switch wire through the firewall which some may find difficult.
The Wireless Version is a Level 1 out of 5 which, unlike the Wired version, comes with Wireless remote and does not require passing any wires through the firewall.
Check out the installation instructions.
Is it reversible?
Yes. It is 100% reversible as there is no cutting or splicing of your vehicle’s factory wires. To restore your vehicle back to factory, just pull out the custom Relay Bypass Module and pop back in your factory relay and it’s back to factory stock.
Will this make my vehicle 100% theft-proof?
Unfortunately, if thieves want your vehicle bad enough–they can pull up a tow truck and tow your vehicle off; no amount of electronics can render your vehicle 100% theft proof. However, the point is to make your vehicle more difficult to steal and make them give up and move on somewhere else.
Will this have any effect on my vehicle’s electronics?
No. Unlike the traditional method of installing a kill-switch, our system/kit does not cut into any of your factory’s systems. Our bypass module acts the same as if you popped your hood and physically pulled out your starter’s relay module by hand (but just much more convenient).

Great product super easy to install. Will be buying it for all my vehicles
Marco –
Great product! Easy to install, it took me a minute to figure out how to make it work but once I figured it out it works like a charm! Only complaint is the customer service, they never message you back and I messaged multiple times about the product. It took 2 weeks to process the order and then the 3rd week it was shipped and then took an additional week to receive. Took a month to get but it does work.

Very easy to install. Hiding wires was a breeze and also toggle switch. Once I received the reverse relay switch it worked like a charm. Staff at 41twentytwo very attentive and service oriented, thank you.

The product works great 2022 Toyota 4runner, but more importantly the company took care of my mistake Right Away. Thank you

Installed on my 2003 Nissan 350z, the type 2 relay kill switch worked great with no issues at all! I emailed the Team and they were great at helping me get the right type of relay ???? I would highly recommend this product on any Z cars!
Cody Anderson –
Works as stated. Couple of notes – Tacomas use the reverse relay. It would have been helpful to have additional butt connectors or better yet, a quick connector to plug the switch to the main cable. Certain switch hiding spots prove challenging to mount and route the wires without quick connects. Another note, the negative ground and the switch wire from the “control module” are not distinguishable from each other. I unplugged both and luckily remembered which was which. I don’t know what function the control module serves – it’s just a box with a cable wrap inside. Overall, worth the peace of mind in SoCal with so many tacos getting stolen.

Easy to install, however, make sure you do your research. Unfortunately what I thought was the starter relay on 2024 integra was a different relay. Starter relay is built into the circuit board relay and so unfortunately this product won’t work with my car.
Brandon –
Switch works perfectly, just wish they have longer wire. But other than that, it works the way it’s described!! Love it!
Omar –
Small switch, easy to install and works perfect.
Thomas Anthony –
took 15 minutes to install and works great. Highly recommend.

It works! It took me a long time to install mostly because I assumed the starter would be under the hood (in my case it was the cabin), so I had to go back and once I had it all plugged in… nope! But then you HAVE to check the instructions. If I didn’t go through instructions, I wouldn’t have realized that the extra relay they provided (reverse relay, essentially swaps position of a third link) in my kit was to swap out incase it didn’t work! Once I had it swapped out, it worked perfectly and I was ecstatic. I had already been working on doing my own killswitch but never finished it because the fuel pump wires were in a hard-to-reach spot. With this kit, it was really easy to install (minus the complications of figuring it out in the first place), and would highly recommend getting one for your vehicle if yours supports it! I’ll definitely tell other car people I know too of this tech. And be sure to know your starter relay location beforehand!

Installed in a 2005 Jeep TJ. Super simple install and mounting with no drilling of the firewall. Just ran the switch wire through an existing grommet. Microswitch is very easy to hide and just zip-tie the excess lead to any harness loom.
I did use some better self-adhesive, shrink connectors for the switch, as the ones included with the kit are just standard crimp butt-connectors. And used a black sharpie to hide the red cover on the toggle: Makes it disappear in the recess where I hid it.
Works great. Also, if something ever goes wonky, simple enough to just pull out relay and pop in the stock one.
People always say the best anti-theft is having a manual transmission, but this extra layer just helps. Great price for the kit, too.
Thanks very much!

I have been meaning to come back to this page to put my review on here but with all the thefts lately it reminded me. Jeeps have been disappearing left and right lately in my neighborhood and have been a hot commodity. I wanted to take any and all precautions to protect my baby from getting stolen even though it is a manual and that is protection in itself nowadays. Lol. I was recommended this kill-switch by my friend. Let me tell you when I say this was such an easy install. I am not mechanically inclined AT ALL but the hardest thing about this was figuring out where to hide the toggle where the typical thief isn’t going to think to look or feel for it. It was so easy to actually install this that I did it by myself without having to ask for help from my husband or son. I have also put on locking hood latches to try to stop thieves from being able to pop my hood open to clip alarm wires and follow this wire. Lastly, I’m getting me an old-school Club to try to deter those damn thieves. 6 jeeps in the last 4 days have been stolen. So glad I bought this kill-switch and installed it last year. This is the best kill-switch and the owners were super helpful when I was purchasing it back then. Super fast with communication back and forth through FB messenger back then since we were in the same local Jeep Group. Thanks for the help NP????

Jus installed my kill switch from 4122 on my 2017 toyota tacoma. Works as it stated. Awesome product & the shipping was quick. Highly recommend????????
Miguel Ortiz –
I installed this kill switch on my Tacoma TRD sport 2023 and it has worked very well for me.
Stephen –
Easy installation, product came with all the required items.
j.R. –
Highly recommended theft protection for your ride. Went with the wireless version. Install was very easy. ’21 Tacoma TRD Off Road w/ push start required the reverse relay. Also picked one up for the wife’s ’20 Rav4. Awesome product, thanks 41.22
alan ramos –
Getting it shipped took 8 days, but not a big deal. They’re backed up in orders. The kill switch is worth it I think. Easy installation for my specific truck. I love the fact that they included the latching switch instead of toggle. Better to hide. I added another switch in series, I mean you can add as many switches in series as you want in different hiding places. I had to use the reverse relay. Thank you!

installed in a 2019 jeep wrangler rubicon.
note: I installed the drop in unit with out the remote. You still need to connect the ground wire to the battery for it to work. Other than that find a nice hiding spot to install the push button kill switch.

Got the wireless version for my 2025 Gladiator, install was crazy simple, and quick! It took me longer to hide the wiring than anything else!

This kill switch is a great addition for your vehicle. I installed it in my 23 Tacoma TRD Off Road and installation was very straightforward. It works exactly how it supposed to. However, in my particular situation, this is definitely a kill switch. I was driving in a parking lot and inadvertently bumped my switch with my work boot and my truck shut off! I contacted 4122 to see if this was normal. I was contacted by 4122 and informed it was not and that I possibly had installed the kill switch incorrectly. I was even sent photos to show the proper placement of my relay switch. After double checking the photos I received and the installation of my relay switch, it’s definitely installed correctly. I still love this product but I think I’ll be uninstalling it this weekend because I feel it’s a safety issue if I bump the switch while I’m driving down the freeway.
Brandon Talania –
I just installed this in my ‘23 Tacoma. Install was fairly simple with the exception of a couple of minor hiccups that I was able to fix myself. One of the connectors came off of the relay wires however I just fixed it with my own butt connector. When I got everything connected and tested, my truck did not start with the button pushed in. Luckily they included a reverse relay which solved that issue and the kill switch worked as intended. The hardest part was choosing a location to hide the switch and tucking all the wiring. Overall, this is a great product and I am happy with my purchase!

The product itself is good which is why I gave the 5 stars, but not worth the price I paid. If you live in Canada the actual cost to you for this $108 USD kill switch will be $255.42 CAD, just want to make Canadian buyers aware!
Kill Switch: $108 USD
Delivery: $30 USD
Total Cost after exchange including taxes: $194.17 CAD
Fedex charges to customs: $61.25 CAD
Total cost: $255.42 CAD

I highly recommend this product, it’s easy to install and it definitely gives you a peace of mind. It was installed on a jeep wrangler JL due to the high vehicle theft rate!
