Fitting a kill switch? Fuel pump?

[DanMAYTEE]

What's the best way to fit a kill switch on a Mk1? I was thinking of doing it to the ground of the fuel pump but I'm not 100% on what I'm actually doing.

After realising how easy it is to gain access to one of these without the keys I'd prefer to have some extra security in it as it doesn't have an immobiliser.

If anyone has any info that would be great

if they want something that bad they will take it however they can. just get a massive steering lock

Put a switch in somewhere on the power to the fuel pump and hide it somewhere. If they do get it started at least they won't get very far with it before it runs out of fuel.
