hidden switch against thieves
I'm considering where I could install an hidden switch, that the truck wouldn't start anymore.
Don't know which contacts of the ignition switch or any other line to interrupt. The switch should not affected to high amps. Is there need for a relays or does it do a simple line to disconnect with a switch?
Any living examples working easy and effective?

I would kill switch the negative side of the coil or use a module kill switch. Then a power jumper to the coil + isn't going to work either.

Slightly different way of getting there but my truck has an electric fuel pump. I hid the on/off switch up under the dash. I can reach it and turn it off. It might start but they're only going to get a block or so before the carb runs out of gas. Later, Shortbox4x4

Put a battery disconnect switch in the negative battery cable.....you could hide it in the core support, put it in the firewall so it is accessible from inside the truck or mount it under the front bumper.......also handy when you are working on the truck to effectively disconnect the battey.......Caterpillar even sells a style that uses a key.......

I have a kill switch to ground the - side of the coil. For those that already have a tach installed, it becomes an even simpler installation to ground the tach lead wire through a hidden switch.

My hidden switch against thieves is putting the transfer case in neutral and yanking the batt terminals off.
Thieves generally cant drive stick, and they damned sure lose their minds when the t-case is in neutral.

":I would kill switch the negative side of the coil or use a module kill switch."
This seems relatively simple right? Just run the negative coil wire into the cab with a hidden switch? Then the other side of the switch back to the coil?

Can hack into the wire harness under the dash. The ignition coil + Positive feed's resistor wire is in it which runs from near the fuse panel to about middle of dash. Maybe add a 30Amp fuse inline as well for safety.
Would need to have good wiring diagrams to sort out which wire.
edit: Complicate it where Nobody wants to touch it! stuff in EFI, and add piles of unused wires just to confuse everyone!
