Welcome from Connecticut, happy and safe camping, enjoy and have fun. Glad you stopped by PopUp Portal.
As for your question. The turn signal wires are used as stop lights also. If your TV (tow vehicle) has separate brake lights, a taillight converter needs to be installed on your TV to combine the stop and turn circuits.
Here is the wiring for the six terminal plug if you have one. The blue wire is for electric brakes (if equipped.)
Thank you Raycfe, for your response. We recently bought this Pop up and our first outing with a pop up is scheduled in two weeks. I thought it would be cool to make a solar charging system for this camper because .. well, it's a camper and not a tent. (I'm also very new to solar as well.) I noticed the cable to the T.V. was trashed and so I wanted to replace it. The cable at some time in the past had been modified to go from the Coleman 6-wire plug on the trailer to a 7 plug connector for the TV.
As I could not get any lights to turn on when I charged the Blue wire I got a little confused. (I'm a carpenter by trade and have never worked on a trailer and rarely work on cars.) I had all the other wires (ground, left, right, running lights tail,) figured out. A previous owner hooked up the Coleman gray wire to the 7-way yellow wire.
The other thing that is confusing me is that the blue wire on the camper/trailer is tied to a 30 amp fuse with a lead that is connected to the negitive pole of the battery. ? Any idea what that does?
And hey, what are you doing on-line on the 4th of July?
Thank you so much for your help!
Does your PUP have electric brakes? If so you may have a breakaway switch that is connected to the battery.
A breakaway switch works like this, The small cable gets attached to the frame/hitch of the TV. If the trailer gets disconnected, the cable would get pulled out and send full power from the PUP battery to the brakes, stopping the disconnected PUP.
As for being home on the 4th I work tomorrow and don't like all the traffic. So I took a nap, cut the grass, took Quincy (dog) for a walk, and went for a motorcycle ride.
