If you will be using a 4-way connector as the trailer connector from the tow vehicle to the trailer the extra wires from the 7-way would not have anywhere to go and would need to be taped off and tied out of the way. They couldn't be also used with 4-way wiring.

I attached a help article on trailer wiring that has several helpful diagrams for you to check out as well.
