Could I get some help with an Electrical Problem?

A light fixture will have a white and a black wire. Install a new white wire from the existing light to one terminal of each of the 4 new lights. Install a new black wire from the existing light to either of the switch terminals. Run another new black wire from the other switch terminal to the unused terminals on each of the 4 new lights. Black wires go to yellow colored terminals, white wires go to white colored terminals.
