Message: [QUOTE="Jaybird, post: 1529358, member: 31266"] First post here on PSA. My issue is a little weird to me but someone else might know exactly what is is. I got this truck (2000 F350) about a year ago and just replaced the trailer wiring plug after the old one being zip tied on for so long. I finally went to use the truck yesterday to tow one of our trailers as our f550 was down. After I coupled it together I found that I had no left side trailer lights. No turn, running, or brake lights. This is where it gets interesting for me at least - I had no power at the 4pin on the truck where it should be, I had constant power at the 7pin on the truck, and I had constant power at the pin on the truck where the trailer sockets plugs into the harness behind the bumper. Does anyone know what to look for before I tear into it? Connectors? Fuses? I just bought this plug in yesterday from the stealership and would hate to have wasted all that money on a broken plug. Thanks! [/QUOTE]
