1968-1974 C3 Door Ajar and Under Hood Anti-Theft Switch 3929804 - OEM Number(s) (3929804)
Keep Your Classic Corvette Secure & Smartly Alert
Don't let a small part leave a big vulnerability. This 1968-1974 Corvette C3 Door Ajar and Under Hood Anti-Theft Switch is a factory-correct solution designed to maintain both your Corvette's security system and convenience lighting functionality—just like GM intended.
This switch performs double duty: it triggers the warning light when your door isn’t closed all the way and communicates with your under-hood anti-theft system. If your original has failed—or worse, been bypassed—this OE-style replacement helps restore your C3's original protection and alerts.
Why It Matters:
Without a functioning switch, your Corvette may leave you unaware of an ajar door—or worse, unprotected from tampering under the hood. Keep your ride period-correct and secure.
