Thanks for the comments. The instructions on the disconnect said to install it on the negative terminal.
I know there is a more elegant way to do this... But this method is effective. I may direct wire the break away system directly to the battery.
I found some nice waterproof disconnectors with a knob last night. 30-60$ depending on what you want. I think that would be a cleaner install. I probably will do that in the near future and make it look cleaner. Plus I won't have to open the battery box to activate the kill switch.
Thanks for the tips, keep them coming. When I go for the cleaner install ill document it here if you all are interested.
Thanks!
