I thought I was right. Just nice to know I'm not
I would rather just have keyed power. Prevents someone from bumping a switch and turning on something that could kill the battery.
This sounds like a winner of an idea! Actually now that I think about it, I have a fuse tap already installed for my interior LEDs. They only come on when I have the parking lights on.
My setup, I am constantly having to keep lights on in the dark. Plus having dual batteries, I have the accessories isolated to my second battery. Otherwise would have done the fuse tap or multi bussed on the block itself.
