How do you remove gas tank?

OK. I'm into the fuel system work and want to take out my tank. The previous owner had a thin piece of metal strap across the bottom of the tank. I cut it and fully expected the tank to drop down a bit. It didn't. I've got the fuel and vent lines disconnected. Do I need to disconnect the wiring before dropping the tank? Appreciate any help and guidance, diagrams, writing directions with pictures, youtube videos, napkin with a diagram, etc
I don't want to start prying on this thing and do more damage than good.

Thanks,
Bob
