Expert Reply:
Hi Joseph; you don't want to add a 7-way as the wires on your 4-way won't have connections for a 7-way. Your 7 wires are three ground, left turn/stop, right turn/stop, and two taillights. What you'll want to do is use a wishbone style 4-way, the 4-Flat Connector Wishbone Style # W002230.
The three white wires are ground, the two brown are taillights, the green is right turn and the yellow is left turn. One of the white wires will be grounded to the frame so you'll splice the other two together then connect the rest of the wires by color to the # W002230.
I have added a link below to a help article on trailer wiring which you may also find useful.
