Expert Reply:

From the image you attached, I think what you have is each of the taillight circuits on your 4-way have two wires ran to them for each side of the trailers wiring. You can wire the two wires of each pin to the single wires of a new 4-way allowing the circuits to get the same signal. Depending on how much of the wiring length needs replaced, you can use the Hopkins Endurance Easy-Pull Harness w/ 4-Pole Flat Connector, # HM38134 for a short length. If you have damage to the last few feet of your harness, and need to replace the end portion, I recommend the this Hopkins 4-Pole Flat Connector, # HM38134.

If you need/want to rewire the entire trailer from lights forward, I suggest the Hopkins Endurance Easy-Pull Harness with 4-Pole Flat Trailer Connector, # HM38136 for 25'. Or, for 30' length, Hopkins Endurance 4-Way Flat Trailer Wiring Harness, # HM48265.

Please note the linked product video below showing installation.
