Could you elaborate a little more? I don't know what battery disconnect ***** are. Maybe others do.

On my classic cars I put it on the positive. Why would you need one on your vette. ??

I don't need it on my Vettte but on a motor home.

To the previous poster, this is a device that clamps onto one battery cable and then the device itself clamps to the battery post. It has a **** that when you turn it CCW it kills the power. Easier than disconnecting the cables.

NEG !!!!

Is the first terminal to be removed otherwise you could get a spark. That is not what you want around a battery. Could Explode in your face.

Either one. Electrons don't know right from left or up from down, without a reference.

When you are disconnecting a battery you want to disconnect the negative first since the car body is connected to the negative and becomes a reference so that if you disconnect the positive first and your wrench contacts both the body and the positive terminal at the same time you are putting a dead short across the battery. Your wrench will get a chunk bitten out of it. Ask me how I know.

But your switch can't make that mistake so it doesn't matter. It either completes the normal circuit or it doesn't and it can be anywhere in the circuit to do that. It makes absolutely no difference.
