Wires/trailer hook-up

[APXD 30]

So I'm almost towing but I have a question about the Red and Black wires on my trailer that seem to have no home in my application.    Do I need them?

Here's the background:

The dealer installed the Pollack part and my brake controller (Drawtite Activator III) and I have the Uhaul adapter for the LEDs on my trailer.   This is a crazy part to allow Cayenne tow trailer with LEDs.

My trailer lead had a 7 PIN plug on it to fit a Denali (purchased from an RTR member). The problem is that the Uhaul adapter starts accepts a 5 PIN and converts it to a 7 PIN.

Here's my question, my trailer has red and black wires. I believe that Red is "AUX/Backup" and Black is for "12V+." My trailer is a simple open unit with brakes, lights, and an emergency battery.

I think I just need to put a 5 PIN end on to be in business and connect the White, Blue, Brown, Yellow, and Green wires. Will not hooking up the Black and Red matter?
