Battery Kill Switch

How about an electrically operated kill switch, operated by a separate electric circuit running from a dash mounted switch to a real heavy electrical switch near the battery?

Lets be clear on terminology - its not a "kill" switch on a 928. There is no place on the stock wiring where a switch can be added that cuts all electric power to the vehicle and will stop the engine.
So its a Battery Disconnect Switch, if you turn it off while the car is running - it won't stop running, but you may do horrible things to your expensive electronics units when the alternator's regulator suddenly had no ballast to run into - voltage regulation will go to hell...
Mounting the switch anywhere where you will need to extend the wiring is a really really really bad idea... don't do it - you will likely create new reliability & functional issues.
Remote control switching (preferrably a latching relay) is possible but adds one more thing to go wrong.
While painful - fixing the root cause is probably actually easier, you just need the right tools, the right knowledge, determination and attention to detail...

If you just don't want a dead battery get one of these (drain sensing auto disconnect, push button reset).

Another reason I went with a switch, doing that wingnut in the dark on a regular basis was starting to muck up the threads, which rapidly gets worse.
Moroso sells a side mount disconnect switch I think would work MUCH better than the one I used, but I couldn't find on locally.

I was talking with Dean Fuller a while ago about these. Reckoned it would be pretty handy to have a key operated kill switch (like the one you show Tony) and install it directly to the rear of the parking brake handle. It would add a lot of extra (heavy) wire though. I've never had parasitic drain hit my battery, but he has been fighting it for a while
you dont realize how handy it is until you use it for the first time.
