camper (trailer) plug designation

[wangotango]

I've got a harness coming out to my hitch.
It has 8 wires. These 8 wires are coming out of a loom to the hitch plug. Factory truck stuff.

Wires are :

white / 10 ga
black / 12 ga
red / 12 ga
lime green / 18 ga
brown / 18 ga
yellow / 18 ga
green / 18 ga
and a capped-off lite blue / 18 ga

Trailer functions are just fine, I have no problems with it.

I'm tapping into the wires for my camper.
Won't need elec brks of course (big blue?)

Can anyone designate these wire for me?

Thanks ....w/t

Thanks Tom.

I do have a service manual for the truck but couldn't find a description of plug.

I understand that the trailer wiring has a circuit of it's own w/ fuses of it's own.
