help w/ identify wires for 7-way

2000 f-250 7.3
took off the 6-way and replacing with a 7 way. not sure about 2 wires though.
i have the turn lights, ground, trailer main, and electric brakes (5 total) hooked up correctly.

i have 2 wires left; brown w/ white stripe and black w/green stripe coming from the factory harness. not sure what these are.

on the female 7-way i purchased; which i am wiring into the factory harness;
i have black wire(auxilliary power lead) and a purple wire(reverse).

not sure which wires go each other.

take a test light to the wires on the truck, the 12v power supply will be on when the truck is on, the backup light lead will only light when it's in reverse, simple.
