Theft deterant. What do you use? Options

[surfdogskier]

We just had a car show up here in Pigeon Forge the last couple of weeks. As usual every year, a bunch of cars get stolen. An I mean nice collectables. I would think it would be a no brainer to put some type of theft deterant mechinism on these babies.

What do you guys use on your rides to help make sure your baby is where you parked it when you come out of wherever?

Looking for some ideas and details.

Thanks,
Jason

For cars with an electric fuel pump, a kill switch in the fuel pump circuit is always good.

If parking a car that uses blade fuses for a while (airport, etc), make a dummy fuse by drilling through the fusible wire portion. Then replace the EFI/coil/fuel/etc fuse with the dummy fuse while parked. A smart thief who is familiar with the car might look for a kill switch or missing fuse when the car doesn't start, but won't probably won't think to pull all the fuses looking for a bad one.
