Be sure to look through ETRAILER.com online... They have lots of info on how the wiring is done with lots of videos and drawings... Even wire colors but you never know what the manf ran...
Might give you some clues...
Also a great place to purchase safety lights and parts etc...
Etrailer was a great place for me going through my wiring a couple of times... I was always pulling my wiring out driving back off road through the high brush. Finally got smart and put everything under the trailer in PVC tubing haha... The PVC tubing hugs the trailer frames and comes through the flooring using PVC Electrical junction boxes with lid access on the bottom... Cut a large hole in the bottom of the PVC boxes to route up into the top side cabinets etc... All neat now and got to seal up all of the bug and insects hole to boot...
Kinda depicted here in this drawing for my POPUP... Under trailer wiring PVC tubing shown in BLUE...
