Adding 7-Way to Trailer with Yellow Wire Instead of Purple
Question:
I have green brown white yellow blue red and black no purple so considering your diagram which would take place of purple since i do t have that color? Thanks

Expert Reply:
Most likely the yellow wire on your trailer is what carries the reverse or auxiliary power circuit and would be connected to the center pin of the 7-Way like # PK12706. This would line up with standard 7-Way wiring for a 5th wheel or travel trailer. I have attached an image to assist.
With that being said it's still a good idea to test the wires for function as it's very possible a previous owner or even the manufacturer could have used non-standard color wiring. You can apply 12V power to each of the wires you mentioned to see what function on the trailer they activate.
