Engine off switch in a Toyota Echo

[johnnymac]

I want to install a bush button momentary off switch somewhere, to turn off the engine in my 2001 Toyota Echo. Where in the wiring would I hook it up?



THANKS!!

Its always easiest IMO to cut wires inside the cabin so you don't have to run wires to the engine bay. Either way though works fine.

Here are options for kill switches:
