Default Secret Engine kill switch

Hey guys
i am always paranoid when I park my C5 somewhere in public.
i would like to put a secret switch that will prevent engine from starting.

what electrical component is the best to Have the switch wire connected so the engine won’t start ?

I love my C5 I would be devastated to see it stolen.

thank you

These days you have the best anti theft device. It's a manual transmission 🤣

Good Day Eric,

Have you thought about putting a tracker in your C5? No larger than a key fob and you can put it anywhere in your vehicle. So even though they might get your C5 you will know where it is and can handle appropriately. On the other hand I heard of some aftermarket key fobs that are used to start the vehicle can also be programed to kill the connection but I don't know much about the device. Cheers!

I wouldn’t worry about getting your Corvette stolen !!…Hondas, Nissans, and Toyotas, are a more desirable car to steal !!

I would have to defer to this article in our own forum...https://www.corvetteforum.com/articl...ettes-by-year/

California has the most stolen vehicles simply we are a populous state and one of the favorite stolen vehicles aside of what you mentioned is our Vette.

Cheers!!!

i am worried by the time they track and find my car, it will be parted out, or taken for a joy ride and destroyed.

as the c5 becomes more valuable the chances get more and more for it to be stolen,
and the LS1 Itself is much loved by other car enthusiasts to do a swap.
I would rather have something that will prevent it from starting.

Good Day Rob,

Not disagreeing with your stats but the stats I was refering to do show that from 1981 to 2011, 14002 Corvettes were stolen in Cali making it #2 on your list.

Eric...on that tracker unit I was mentioning, it has real tracking which you can track yourself on the web or your cell. Many of them also have notifications sent to your email, cell or whatever. Cost's me $25 a month and for me that's good insurance. Cheers!!!

No problem but you can’t compare a 30 year period (1981 to 2011) to a YEARLY number on my list…that’s all !!!

I realized after putting on the LMC5 on my 1999 Convertible with manual transmission, someone or a couple of people could just pull the shifter out of gear push car and steer it away or up to trailer with wench, with only having the door open or even window down.

That seems easier than them trying to Hotwire car or pop hood and use jumper wire to bypass relays.

Was watching some show about gang members and how they steal cars in San Diego and So California to slip into Mexico to use for cartel reasons.

It was a recent show and they had the “gang member” blurred and voice changed to show how easy it is to steal a car, a early 1980s GM car he broke ignition switch and started car with screwdriver.

Had to double check and show was 5 years old tops, started laughing because those cars are not around much nowadays.

Worry about my 1965 C10 short bed fleetside custom cab, it’s rough and aged but these are not around like they once were, it would be easy to steal, any key fits the well worn out ignition key hole.

Could replace it, but they could just go under dash and hot wire it, however just put Edelbrock pro flo 4 multiport fuel injection on the 396 big block, maybe a switch to cut off electric fuel pump?

My fear adding cutoff switch is a malfunction or switch gets bumped off accidentally going down freeway that is crowded and engine dies, trying to pull over quick with dead engine could be way of getting in wreck or rear ended, and possibly hurt bad or even killed.

This could be old truck or a C5, bad situation engine just dying going down crowded freeway.

Maybe just pull a relay under the hood when you park it, then pop it back in, this would be free and probably less likely to make engine die in a bad location like freeway?

On top of that, you could get a used or even new relay and cut or break off the spades, cut off the 2 that are for control part of relay, or leave those and cut the spades off for the load side of relay.

Thief pops hood and looks, sees no missing relay.

If someone really wants your ride they are going to get it.

back on track instead of arguing if the car is actually gonna get stolen.....

I've not installed one in my current car, but in a previous car I installed a hidden fuel pump kill switch. small switch hidden under the driver's seat which disconnected the fuel pump circuit via a relay. There is no way a thief would ever take the time to track down what was 'wrong' if he got it cranking but no start. of course that would not protect it from just flatbed / towing, which is apparently what is often done by the pros.

good luck op!

My second option would be custom built pedal lock.

I have built one for my 2018 Tacoma, it locks all 3 pedals and uses a type of lock that it’s practically impossible to cut

but by looking at the way pedals are on the C5 it will be very large piece of metal and very complex

Another option which I use in my 68 Camaro is to pull the battery out when not in use. I relocated the battery to the trunk back when I was going down the 1320 and I also had a rear mounted "kill" switch as NHRA rules specified. When daily driving her around (not much though) I also incorporated a lock cover for the switch to keep passerbys from messing with it. I know it's a little work to take the bat out every time but it's worth it to me. Cheers!!!

the reason I wanna put the switch is because
let’s say I go to have a dinner and I parked my C5 in the parking lot I wouldn’t wanna take the battery out or open the hood.
that’s complex.

with a Small kill switch, car will be disabled

I would convert one of the CID switches to disarm the starter with a relay under the car. If it won’t start or run, the very first thing is to look for a kill switch in the usual places; under the seat, glove box….

If a thief has the ability to jack the car up, and the skill to chase down that problem, that probably excludes amateurs and opportunists.
