Negative shut off switch

[NastyNate98]

I just purchased a clean 98 two door tahoe and I cant park it in my current garage because my garage was apparently made for a miata. I am moving in May but in the meantime I would hate for my hoe to get stolen from my driveway. Instead of an expensive alarm system I was thinking I could install a negative battery wire shut off switch under the dash. That way I can shut it off overnight, and even if someone broke in and tried to steal it, they would never have battery power. Thoughts?

Good thing you’re moving sounds like a good idea.

Years ago I knew a guy that rigged some kind of switch under his driver's seat. If the switch was pressed down(sitting in the seat)the car wouldn't start. You actually had to start the car, standing up. Actually pretty smart, until the 1st time it's pouring as you're trying to start your ride. This would prevent a thief from driving your rig away tho.

Pull the fuel pump relay

Agreed. Fuel pump relay is the thing to disconnect /switch.

I want to be able to switch it on and off from inside the truck, instead of popping the hood every time. I'm going to move forward with this plan. Was just curious if anyone had done this before.

Yes! I had a hidden switch under the dash for the fuel pump. It was covered/hidden by a vacuum hose but I could even activate with my foot if I were carjacked. Such was a popular pastime of hoodlums in the early 1990s. This switch was placed in between the computer and fuel pump.

We also had a device that was then called the Touch-N-Go. No, it was not for pilots, you had to touch two parts of your car to complete the circuit so it would start. Here it is:

Wow I've never heard of this. Pretty cool! Too bad I have airbags and cant use it. But with the negative shut off switch I can also save my battery juice if I let the hoe sit for a couple weeks.

I think the downside to that is that every time you start the engine after having cut the battery power, the engine and transmission will have to do relearns, same with the AC. And this can take days to settle down unless you hit the kill switch every night and then it will never really relearn.

Yup. If you're going to leave it alone that long, just disconnect the battery. For everyday security, put a hidden switch on the fuel pump relay.
