Question:
The dog chewed up the flat connector on my trailer which has five wires, white, green, yellow, brown, and black. I bought a four wire flat connector at Autozone, for the trailer, but only offers a four wire connection. Do you run two of the five wires into one connection position, and if so, which ones? Or, does the black wire even need to be connected?

Did you have a 4-pin connector that had 5 wires or was it a 5-pin connector? There is a big difference since you normally see a 5-pin connector on a boat trailer with the 5th pin used for an electric reverse lockout solenoid on a brake actuating coupler. If it was a 4-pin connector with 5 wires then it is called a wishbone harness and would have 2 wires attached to the running light pin so you have one wire for each side of the trailer.
Typically, on a 4-Way, the white wire is ground, brown is running lights, yellow is left turn/brake lights, and green is right turn and brake lights. A 5-Way will have the same functions but then usually a blue wire at the end for that electric reverse lockout I mentioned.
On a wishbone 4-Way you would have a ground wire and then you usually see a brown wire with yellow stripe for the left side running lights and a brown wire with green stripe for the right side running lights. They are attached to the same pin. All of the other functions are the same.
