EC Iowa | Anyone know how to wire a 6-wire car trailer w/ brakes to a F350 Ford, that has a 7-wire trailer hookup. I don't have an owners manual for pickup but looked online for wiring diagram but gave me choices, I couldn't figure out. TIA |

| Tractor supply has trailer adapters for that. There like 15-20 bucks. I have the same scenario for my pick up and stock trailer and the adapter is what i use. |

| Industry standards:
Left turn: yellow
Right turn: green
Trailer marker: brown
Ground: white
Trailer brake: blue
Aux/battery charge: red
The last one should be reverse lights not needed on 6 wire round
Your trailer wiring harness should have those colors, if not just use a test light to chase the truck wires.
I always use die electric grease when making terminal connectioms, and I always put it on the pins of the female connector. Once I started doing that I had less roblems.

WY, OK | Factory Ford plug lids have the pin layout printed on them, at least for the last 10-15 years. |

Northeast Nebraska | Industry standard? LOL. You are kidding right?
Okay, maybe for vehicles, but 7 ways (RV plugs), semis, and pickups all use different colors and terminal locations. I had the pleasure to install a flatbed recently and mis wired both of the RV plugs I installed.
This chart is accurate and is the best I've found.
WARNING: If you buy a Curt brand, ect. plug, it will have printed on it what color wires go where. IT IS WRONG. atleast for pickups it is wrong. It may be right for an RV, but I'm not sure.
USE THE CHART

| In a world of standardization, trailer wiring is far from it. Both wire color and pin position vary by application/industry. The most common common color coding is; green-right turn (think turn when clear), yellow-left turn (think turn with caution), red-stop (be it lights or electric brakes), black and/or brown-tail and markers, blue-aux (be it back-up lights or whatever, and white-ground. The ground pin/socket/lug is larger than the rest.
Pin position/useage is not as standardized. It is not unusual to find mating connectors to be labeled differently. The adapters can be equally challenging. |
