I've installed one of those or a similar product about 15 years ago. Its a mill-spec connector and cap which breaks circuits when the cap is removed. IIRC it has quite a few extra wires intended to confuse the would be thief. It would be effective on a mid 90's+ vehicle. Our cars are too simple. Ford was kind enough to provide everything needed to hot wire the car at the solenoid if you have a 2' alligator lead to connect to the coil and a screwdriver. If they can get the hood open you're screwed and if it's a manual and they can push it they wont even need the screwdriver. I used to install a lot of hood lock cables on classics. It mounted under the dash and used the round vending machine type security keys. when you pushed in the lock the cable would slide into a receiver that mounted by the hood latch. It also had a wire that you could connect to the coil that grounded when locked. I'll see if they're still available. The Club will loose to an aggressive tooth hacksaw blade every time because the steering wheel takes literally a few seconds to cut through. With all of the 24 and 48 volt cordless saws out there now forget it.
A standard alarm will make some noise before they disable it if you're lucky, but it fails for the same reasons I mentioned before. If you do opt for an alarm go with Code Alarm or Viper/Clifford (expensive ) as top tier. I sold Autopage until recently as the company was sold to complete morons. Audiovox, Crimestopper and Compustar are decent too. The trick is to hide it and keep them from getting under the hood. If they really want it they'll just tow it. I install more tracking systems than alarms now. They range from $350-475 installed for the unit and $5 to 15 per month depending on features. The advantage is that you can locate or track it on your smart phone or computer real time and it can email, page or call you if tied in with an alarm system. I have a feeling quite a few are to keep track of cheating spouses. They're handy for the kids too as you can set it to give speed alerts or set up a geo fence.
My son will be driving next year and he knows he's screwed. mwahahaha!

they came in several sizes up to 12' I believe.I would use that along with a standard alarm.
