As noted above, placing the disconnect in the battery "hot" cable rather than the battery ground cable would not protect against the hazard creating a dangerous, high-amp short when removing the "hot" battery cable from the battery post. In that case, it would be necessary to remove the ground cable from its battery post first, regardless of whether the disconnect was on or off.

And that would kind of defeat the whole purpose of having a 'kill' switch, wouldn't it?? In my limited DC knowledge, I cannot see any any other practical solution other than interupting the 'hot' side of the circuit. Chris.

I'm no expert by any means, but there seems to be a split of about 70% of people online saying it should go on the ground side (positive, in my case), and about 30% saying it should go on the hot side. I was planning on going with the 70% people, unless someone can make a compelling case for it to go on the hot (negative) side.
Thanks!

TXGoat - I don't quite understand what a body feed wire is, but would love to learn more. I plan to run a cable from the ground post to the switch and another from the switch to the positive terminal.

You are receiving good advice on this question, but I would find a local expert to install your switch. There is no room for error with high current circuits. Even though you did not mean it, you described a short circuit.

Can you please explain why this is a short circuit? I'm not an expert, but I've watched several videos from guys that do a lot of repair work and they all wire the shutoff switch in this manner. Remember, I'm working with a 6v positive ground. Thank you!
