Wiring harness colors dont match trailer wire colors

[polk county]

The trailer lights on my trailer have these color wires: White, yellow, yellow/brown, green and brown

The vehicle's wire harness doesnt have all of these colors. Also why are there two white wires on the vehicle wire harness? The colors are White, yellow, aqua, teal,blue and brown.

How does this connect together?

thanks for the help

Re: Wiring harness colors dont match trailer wire colors

So pop a tail light and look at the wires. White is ground. Use either one. You will note that one white wire is bigger than the other. The aqua wire is also the same size is it not? That's probably a dedicated circuit for a travel trailer or a trailer that contains a battery that needs charging. Brown is tail/running lights. Green and yellow are left and right turn signals.
