Default Car Alarm

When I was in college, my truck was stolen. Determined to not let the next one get stolen AND not having much money, I made a cheap set up that .... Well at least the truck didn't get stolen.
1. Run a wire to a toggle switch, from any accessory that becomes hot when the engine gets started.
2. Run the wire from the toggle switch to the horn.

At this point whenever the toggle switch is on AND the engine is started, the horn will sound continually until the switch is turned off.
I hid the switch under the seat and turned it on any time I parked it.

Think about it, as soon as the vehicle gets started the horn continues to say on. The thief has the choice to find why, or split and move to any easier target.

If you want to really get creative, get one or two additional horns. If the thief decides to hang around and find the horn to disconnect, he probably won't think to find a second or third horn placed say inside the rear quarter panel and or rear bumper.
