So i decided im going to install a kill switch on my car. I was just looking for recommendations to where i should hook up the switch to. I have seen them set up to the immobilizer, fuel pump and the ignition.

 

You could put a kill switch on the clutch switch as well.

I have one on my clutch and fuel pump. Bad thing is the car can still be push started with your clutch switch open.

Just another idea.

 

The a clutch bypass kill switch is a simple easy method, but as you pointed out it is not extremely effective. Its purpose is time.

There are plenty of kill switch ideas covered in the AVS Forum, rather than recite your options i'm going to link you some references:
