Has anyone hooked up an ignition kill switch or fuel pump cut off switch before? I’m looking to do this mostly for added security. Which one would be easier or better to rig up a switch to? Where would it be easiest to tap into the starter ignition switch or fuel pump wiring?

A super simple way to achieve the same result would be to pull the fuse in either circuit. You could also replace the fuse with a blown fuse of the same amperage/color so nothing is obviously amiss. On my Z24 i pulled the fuse for the fuel pump. It got broken into but never stolen. YMMV

You know the engine won't run without the low res pulse signal from the Opti. Simple switch in that wire.
