Tacomas hold their value for a reason — which is exactly why thieves target them. The 41.22 kill switch pulls your factory starter relay and drops in its place, so the engine stays dead until you arm it back. Here’s how it works on a Tacoma.
Why Toyota Tacomas get targeted
Tacomas are among the most resale-stable trucks on the road, and thieves know it. Most modern thefts aren’t smash-and-grab — they’re relay attacks and OBD-port reprogramming that start the truck without your key in well under a minute. On top of the whole vehicle, Tacoma owners also lose tailgates and catalytic converters.
A kill switch doesn’t stop a stolen tailgate — but it does stop the part that drives away.
Pop the relay, drop ours in, the starter stays dead
A relay attack or a cloned key still can’t crank the engine — the starter circuit is open until you disarm it. No soldering, no cut wires, and it pops back to stock in minutes.
A real Tacoma install, start to finish
Four steps, one afternoon
Pull the factory starter relay, plug the 41.22 module into the empty socket, mount your switch where only you can reach it, and arm it. No tools beyond what’s already in your glovebox. Reverse it any time and you’re back to stock.
Is a kill switch the best anti-theft for a Tacoma?
Alarms get ignored. GPS trackers tell you where your truck went — not how to keep it. A kill switch is the only layer that stops the truck from moving in the first place, and it stacks fine with whatever you already run. It’s the cheapest “no” you can give a thief.
Run your Make / Model / Year + VIN
Most Tacoma model years are covered. The selector on the product page is the authority on exact fitment — it takes about thirty seconds.
