328 Fuse Panel Removal

Switching the relays in the fuel pump circuit didn't help my intermittent starting problem. I know the problem is somewhere around the relay connector because thumping on it usually causes the fuel pump to run. I want to remove the whole panel to check the wiring from the relay socket.

I removed the two screws from the bottom and have the panel dropped down. Do the electrical connectors plugged into the front of the panel just pull out or is there some sort of tab that needs to be unhooked? I don't want to break anything and they aren't slipping out very easily. Same question with the main power connector to the panel. There are two approximately four gauge wires plugged into a thick black connector on the right hand side. Do they just slide out as well?
