Making a car difficult to steal

On a factory wired car with no hood lock, I can have your car running in about 30 seconds with a clip lead and a quarter. And I'm old and arthritic


I'd forget about the start circuit, THINK about it

FIRST thing to do is get the hood chained shut. FIRST.

That's because NO MATTER what you do to the start circuit, if the battery is accessible and hooked up, "I" can still reach "down there" with a screwdriver, jumper across the start relay or starter and crank the engine.

If you use a Mopar ECU, I can still hook a clip lead to the coil and fire the ignition

THESE ARE the key points.

If you want to hide the ignition box under the dash, you could break the power to the box, and it might be hard/ too much time to chase down

If you ground the coil NEG (tach circuit, hint) it won't fire
