Wanting to install a kill switch in my 87 runner. Just looking to see what the best way to do it is and what exactly I need to tie into?

Best way is to wire a switch into the fuel pump. That's how I do it but I dont bother anymore since I never really ended up using it. I tie it into the ground wire and hide a switch somewhere.

^Agree. Fuel pump is the way to go.

I asked this same question a few months back. This thread should help.

Anti Theft Ideas

X2. The truck acts like it wants to start but wont.

You can also splice into the EFI relay and/or the ignitor circuits. All three will waste a theif's time getting it to crank but it won't start. Make your wiring solid but don't make it totally inaccessible in case you need to override it on a trail. It's one more thing that could fail and strand you.

You can do it to kill fuel pump, or ignition, either way the engine won't start.

Fuel pump is also funny because it will start and thief will be like oh yeah then it will die within 5 seconds and he will be confused.

I'd go the fuel pump method. Just go under the back seat access hole and cut the wire, splice in your switch and done. You should hide the switch under the seat, or dash.

If you do end up splicing and dicing the wiring for either the fuel pump, ignition etc; I recommend actually soldering the wires together and covering it with heat shrink tubing. The last thing you want to happen, is to be using butt connectors and have one of them come loose while your driving/wheeling; then be sitting there for hours troubleshooting all the systems.

Oh and another important point; don't forget you wired in a switch in the first place!! It isn't fun sitting there trying to start your vehicle (be MILES away from home) and it won't start because you forgot to hit the switch...ask me how I know!

A buddy of mine had a kill switch to the fuel pump on his Bronco. Two times that I can remember he came to his truck and found the battery dead because a thief had run it down trying to get the truck to start.

Yep... I spend 2 days, off and on, trying to start my Jeep after a month long wrenching session. Then it dawned on me... kill switch.

Cool thanks for all the help guys and I will defiantly solder the wires.

I prefer the basic, low-tech ideas. Less things to break.
Kill switches for fuel, ignition and cranking would all waste a thief's time, and hopefully make him move on to someone else's Cadillac.

How about a second set of horn and horn relay? Connect so as long as ignition's on the added relay-horn combo stays on, unless you turn a hidden switch off.
Basically same as car alarm sound without fancy electronics. Hide and mount horn and relay securely so harder to find and disconnect. Wire so it also activates stock horn.

Then, if he figures all the above out, a timer (ok, higher-tech) that after 5 minutes of driving, will activate smoke generator under dash.

Then, a hidden camera that would record thief's reaction. Bwaa-hah-hah!

Are you this guy?

LOL! Remember I prefer low-tech, with high-tech backup if needed.
I'm sure you'll enjoy the video of frustrated thief when it's posted - LOL!
