Wiring question.
I purchased a 2003 Coachman 25' trailer that had a bedroom that was partially gutted. There is a junction box under the bed. Two of the trailer light wires were disconnected from this box. Does anyone...

My Lance uses green and white for the running lights. If this is a front bedroom, those wires probably go up under the front cap then through the roof to the back. Stop/turn probably down thru the floor and thru the underbelly to the back.
So the test you did at the truck connector with the multimeter.,...you need to repeat that in the trailer. Find all 7 lines that come thru the umbilical and test them to see which is which, it seems like there is no reliable color standard. Once you figure out what's coming in, then you can figure out where it goes. If you pull the back lights you should be able to see what color they used for right and left stop/turn.
