Ok guys this may have been asked before, and TG Twinkie has been helping me some messages.
I have attached a picture of how my trailer 1972 Argosy 20ft was wired to the 7 way plug... one thing I found wrong was the reverse lights were connected to positive (black) wire for the trailer plug that has since been changed. I will be added a connection/junction box... but I have a couple of wires from the trailer plug I don’t know what they would hook to on the trailer side... here’s what I know
Trailer plug into tv To Trailer side
Red Red left turn/stop
Brown Brown right turn/stop
Green Green running lights
Yellow Black reverse lights
Blue (big wire)
Black ???
White ????
I also have a white cable laying down on the ground it is marked in the picture as brake cable, cause that is what is labeled on the cable wire, it has a black and white wire with in it.
Also how can I hook up a new breakaway switch as well... I do not have a battery installed in the trailer... there are wire big wires near the converter and
12 volt fuse panel not hooked up.... black, white, red, and blue... I can post a picture of that later if needed...
any help is greatly appreciated, I am pretty handy, I have changed out starters and dropped a transmission to change a fly wheel before, but the wiring for this trailer plug might push me over the edge.
