I am finally finishing up the installation of my 10kw 5502 and I haven't figured out how to release the factory-supplied N1/N2 wires from the connector at the generator. I don't want to break it! Can the wires can be relased with a tiny screwdriver or similar?

I have run #14 THHN/TWN conductors for N1/N2 which I will need to connect to the terminals at the generator. With the connector accept #14 stranded OK?
push down on the connector with a screw driver,there is a hole next to the wires that are already inserted
14 is ok
