Can anyone tell me how to completely remove the carburetor from my 2000 350S?

I have seen a video on a similar thread that I posted before, but it’s not the exact same carburetor that I have. Mine has what looks to be a nut below the bowl, with wires attached. I think I would need to unscrew that in order to completely remove my carburetor. I tried removing it once, but it was so tight, I was afraid to break it. I could not figure out how to remove the wire from the connection, so that was a dead end too.

Any suggestions?
