I am trying to find pictures and ideas for a battery kill switch. I want to mount the battery in my trunk, but I don't want to drill into my tail light. I am thinking of either using a standard flip switch, and mount in through my license plate. I also like the pull/push type because it can be removed when I am not at the track. I don't like the idea of my DD having a switch because I don't want some smartass turning my car off in a parking lot. I don't want to deal with my PCM or my radio settings losing memory because someone thinks it's funny to flip the switch. It has happened to a friend of mine like 5 times already.

Which is why if I use a normal flip switch, I will make a connection across the two posts inside the trunk, making the switch useless....and I will just remove the link when I go to the track. But I also like the idea of the push/pull type because the handle can be removed when I am not at the track.

Anyway, I am looking for pictures of different types of kill switch setups. Thanks.

I drilled right next to my taillight. Just moved the licence plate over ever so slightly.

i dont understand the point of isolating the battery from the system... i know alot of people do it but wouldn't it be better to have a fuel kill switch? If your car is running and you isolate the battery.... who cares nothing happens. However i can see the point of having a switch that cuts off fuel flow in case of anything. So i bought a battery isolator switch and will be running it through my FP instead... Unless someone has a better idea or a better reason to isolate the battery.

Because if you get in a wreck and one of the 8 foot battery cables gets chafed and grounds out, your alternator will pump enough amps into that wire to start a major fire. Also if you wire the switch correctly, it will cut off the battery power and the alternator, so now there is no power to run your fuel pump, so in effect you are eliminating 3 problems. 1. The alt turns off so it cant pump out any power to the wire and the car cuts off, 2. the battery is cut off so it cant pump power into the wires, and 3. it cuts off the fuel pump, ignition, etc.

I have a 200 amp fuse close to the battery, so in case the wire grounds out when I'm not at the track my car still wont burn down.

I have a moroso cut off switch mounted behind my license plate. When I go racing I just take off the plate.

With a trunk mounted battery you need an external cut off switch to pass tech at the track.

My switch is just a turn style one. Either on or off. The push and pull style would be a bit easier to mount beside the licence plate I think.

That is an awesome setup, thank you. I think I might just go ahead and steal that idea.

when you space the plate out, the plate lights don't exactly light up the plate and could lead to tickets. just some food for thought

Its funny how the simple ideas always amaze me. I never would have thought of doing that.

Yea, that is exactly what I was thinking. I have been killing myself, trying to find a way to not drill into my tail lights and not have a switch exposed on my DD. Then I see that idea, which is insanely simple...yet I NEVER would have come up with that on my own.

stereos and clocks hook up direct to the power source.

the radio should have a yellow wire (after market stereo) which is a constant to the battery. its for memory.

can you run that wire directly to the battery with out it being part of the kill switch?
