Replacement Wishbone Connector for Damaged 4-Way on Trailer

Question

Question:

Is there a quick fix for my trailer? I have a 5 wire 4 pin tip that was drug on the road and needs replacement. Only the plug on the trailer is damaged. I bought a Hopkins quick fix but it only has 4 wires. Not too tech savy so need help.

What you have that got damaged is a wishbone harness, and the Hopkins Endurance Quick-Fix 4-Way Connector # HM48192 will work, but you would need to combine the two running light wires and turn it into one wire. Or you could simply get a new wishbone 4-way # A20WB, cut off the connector and use butt connectors # DW05743-5 to combine the wiring. I've added links to video reviews of these parts for you to take a look at.
