A GOOD system such as a Cobra or Clifford uses an encapsulated box so even if you get it open all the components are within a resin block and almost impossible to work on. Someone like myself with a basic 12v probe can normally get around such devices in a few minuets at most, even the best. 90% of the effectiveness of an alarm or immobilizer is in the installation. Just dropping the under tray off the dash and cable tying the box to the frame and running the wires to the nearest points required is a waste of time. properly concealed (buried) and wiring routed into the original loom and that recovered with the SAME type of tape, soldered taped inline joints not crimp-on connectors or scotch-loks and remote (radio) operated not touch pad and leave out the LED if supplied, it's traceable as above remarks.
If you want a "bugger off, I'm alarmed" LED get a 12v flashing one from your local component store, live to permanent live (+30) and negative to ignition controlled (-15), back of radio is a good place for both, when ignition is on you have 12v at both leads = no LED, ignition off and the negative side goes to ground and one flashing LED.
"Lo loader" is a car transporter.
"Lo-Jack" (USA) or "tracker" (UK) is a covert GPS system used in conjuntion with the police who have direction and strength detecters in their cars and can follow a stolen car at a safe distance and apprehending the */#2## who stole it. Not even the owners knows where it is and they shouldn't even tell ANYONE they have it, there are no stickers or warnings. Several makes / companies, all good. activation is by national digital radio system once the owner has reported the theft and the company phones back to confirm.
Wana stopo your car being driven off in the night or while you are away? Just pull off the HT lead from coil to the dizzy and put it in your pocket.
