Get an extension cord and cut the female end off of it. strip the wires back about 2 inches.
take it out to your truck and route it so that it is not easily seen and have it go up into the engine compartment. take off the radiator cap and put the stripped end into the radiator. close the hood. go back to the house and plug the cord in.
When you hear the scream, unplug the cord and pull it back to the house, then use a tire iron on the perp.
Note, you might want to make sure that your truck is definitely on your property (and not on the street) where an innocent bystander or jogger or pedestrian can come into contact with the vehicle..
Note... this may cause your circuit breaker to trip...
also note... this will probably roast your electronics in your truck...
also also note...you can probably go to jail if you are caught...
So probably not a good idea, but it is a nice fantasy to think of the perp lying on the ground twitching as his eyes roll back into his head and pisses himself after getting a full 110 volts as he tries to open the door...
