The best I've seen....
a guy wired a 'feed-thru' on the negative
terminal where the battery cable bolted
to the firewall. The switch was beside the
passenger (U.S. model) glove box.
For all intents and purposes,... visually
it looked like the standard bolt to the body work.
The ground to the motor came out through a
hole in the fire wall, from the 'switched' side
of the circuit.
You could play with the V+ side of stuff all you wanted
not realizing it was the lack of ground that stopped
you from starting it.
A bit over the top... but VERY effective.
The best and simplest.... just remove and carry
the distributor rotor in your pocket when you leave it.
Come on... how many 'would be' thieves or joy
riders are going to be carrying a rotor with them :-)
