Ignition cutoff switch install

[bobs2002]

I installed an ignition cutoff switch in my '77 Datsun 280Z and a friend asked if I could do the same to her '02 4Runner (3.4L V6). The Datsun still has it's simple OEM ignition system so I just ran a wire from the primary side of the coil to a SPST switch, and a second wire from this switch to ground. The '02 4Runner has a more complicated, high output ignition system than the Z has and I don't want to take a chance on damaging it (if it's even possible to install a similar cutoff switch). Does anyone in this forum know if this install is possible? Should I install a switch to cutoff voltage to the fuel pump instead (another popular method for 280Z's)?

Thanks for your help,

Bob

What is your desired outcome?

All you would need to do is install a switch on the black and red wire at the ignition switch. It will turn the engine off just as if your were turning the key off.

Wardriver--looking for an additional level of theft protection.

Singtoe--thanks for the advice, that's what I'm looking for.
