Wiring in New 4-Way to Trailer that Has Two White Wires

Question:

I am replacing the plug and dont know how it was previously wired. I have a 4 pin it has a yellow brown, green and white. I know I ground from the plug is connected to the trailer. The trailer harness wiring has solid brown, yellow and green wires. I attach those to the brown yellow and green from new plug. It also has a white with brown stripe and a white with green stripe and the trailer harness wiring. What do I do with these?

What you'll need to do is match all of the wire colors like you mentioned and then run the single white from the new plug to the two white wires you mentioned that have a brown and green tracer wire and you'd be set. It's basically just an extra ground wire that would run to the single ground of the new plug.

I also attached a link to a page that has wiring diagrams for more info for you to check out as well.
