Even though my newly purchased ride came with an aftermarket alarm, I
wanted a little extra protection in case some clever bastard managed to
skirt the alarm system and gain access to the cab. I saw a thread about
disconnecting the clutch pedal switch, which effectively makes the
clutch bypass switch act as a 'kill switch'. I wanted a kill switch that
wasn't readily visible. Even a stupid thief might get lucky and activate
the bypass switch without really knowing what they were doing. So,
I went one step further.

I used a simple 6-pole slide switch, tucked up into the mounting bolt
recess above the parking brake. Splice into the clutch switch wiring,
running the splice to the slide switch. Then splice into the wire at pin 1
on the clutch switch bypass, and also wire it to the slide switch. This
effectively makes a kill switch active for both clutch circuits. The
vehicle won't start unless the kill switch is "on".

An easier way to do it is to find the wire coming off the 7.5A "STA" fuse,
which feeds both clutch circuits, and insert a switch. I didn't feel like sifting
through all the wiring near the fuse panel so I opted for the 4 wire install
instead.

Can take pics for those who are interested...just let me know...

Oh yea, DISCLAIMER: This was on a 2002 Tacoma. Can't vouch for other
years/models. Easiest way to find the bypass switch feed is to ohm-out the
wires on the bypass plug to the "STA" fuse.

No offense, but you just told the world about your kill switch...

Anyone with time, and knowledge of wiring would still be able to figure it out.

Unless you have a hood lock, you have only slowed them down a couple seconds. Since they may need to get under your hood to cancel the alarm, it may even be less time.

You have started on a good project, but you might want to give a little less info.

This is true, but most crooks won't spend the extra minute to figure it out. But a real car thief knows how to get a taco running in a few seconds if he can get under the hood.

Some may think I'm giving away some big secrect, but I'm not, the info is out there, and many know it.

I do think that the "Kill switch install" is a very worth while thing to do, they saved a truck of mine once, but I don't do the hidden switch thing.

Of course as long as most Taco's don't do anything to protect there rig, the joy riders and pros are 90% likely to pass mine by.

Try to find me in Hawaii. ;) Ain't gonna happen. There's literally THOUSANDS
of Tacomas over here.

As for time and knowledge, most smash and grab types aren't going to know
what they are doing aside from stealing crap. Even if there's a smart thief
trying to hotwire the rig, it won't turn over without the 12v to the ECU.

How so? The clutch circuitry puts 12v to the ECU. How will the truck
start without that 12v signal? Is there a way to completely bypass the
ECU to get the truck started?

The ECU dosen't start the truck.

You'll NEVER see me post that answer on the net.

Your switch is a good idea.

I've been playing with the idea of a kill switch for my truck but don't have enough knowledge of the wiring and stuff with my aftermarket alarm. I'm not worried about the switch being visible since I've got several switches all over the place as it is. I'd just put it beside one of the light switches. Since none of them are really labelled, it'd blend right in.

Easier way... get a pit bull. Name him "Switch". Anyone gets near your truck...KILL SWITCH!!!

What I did for the 4Runner was use a relay spliced into a very crucial circuit, then, for that relay, I have a single keyed switch, and 4 10 position rotary switches. So basically, its a combination type thing, combined with a key. Its hidden out of the way, but still easily accessible. Its only "armed" when parkign somewhere for long periods of time, or in really shady neighborhoods.

Thats all Im going to say though.
