Any thiefy type may be watching you open the hood and remove some part. Coil wire is real obvious and simple to make or steal another. The rotor is not as obvious but takes longer and the thief if watching will just get another. Kill switch under the dash is quick to find. A momentary switch to interupt the starter enegize wire coupled with a blown fuse under the seat may slow them down enough to get them to look elsewhere.
