Anti Theft Suggestions????

[roadstar]

I have read some posts that some people had wired a relay on the HEI wire as an anti theft kill switch. I am sure that will work but why not put one on the starter solenoid S wire? Looks to me that would keep a thief from cranking until the battery runs down.

Looking for suggestions for anti theft measures besides the usual guns, dogs, and alarms. Extreme measures are warranted in the lovely Memphis, TN area.

Thanks in advance for any suggestions.
