How to Determine Functions of Wires on Trailer and Recommended Trailer Connector
Question:
Can you please help me with the wiring for my 2001 Coleman Sea Pine Camper 7 pin plug. I am attaching a photo, I have determined a few thing but cans seem to get all the wires correct, White is ground Green seems to run the running lights Red appears to be break lights stop Brown Blue light Blue Darker Black I have a tan and black that go to a extra plug that i dont know what it is for. Can you help me figure out how to wire the 7 pin on the trailer. Also which of your plugs is best for me to purchase

I can help you determine which wires go to which functions for your trailer, though there is no way to determine this by color; the reason for that is functions are not determined by the color of the wire and there isn't a universal standard for this.
So in order to determine the functions for your trailer use a separate 12 volt battery and run a jumper wire in order to apply power to the circuit which will tell you the functions of each wire.
In regards to a plug, I recommend a plug and lead for the easiest install, the 7-Way Molded Trailer Wire Connector # H20043. You will only need Butt Connectors # DW05745-5 (12-10 gauge) and # DW05744-5 (16-14 gauge).
I have added a link to a video review of this connector for you to take a look at as well as a link to a help article on trailer wiring which I highly recommend reading.
