Don't try to turn this into rocket science. The Pollak connector has the terminals marked with the correct wire color. If your existing wiring from the vehicle is missing some colors, you are going to have to provide them. All travel trailers 7 way plugs are wired the same and you are going to run into some issues if you try to roll your own.
I am NOT trying to "roll my own" (other than the +12V "key on" vs. "alwyas hot"). I just want to know for certain what is "standard".
It also seems odd to my that there is a pin for reverse/backup lights when few TT actually have them.
