Trailer plugs
Hey,
To start with I have never been any good at hooking up trailer lights.
But I always try.
This time my brothers small trailer is the progject.
His trailer has 5 wires :1. Green 2. Green Brown.3. Yellow 4. Yellow Brown 5.White
But he has a 4 wire plug.
The plug has 1. White 2.Brown 3.Yellow.4. Green
Please help, I'm not sure how what wires to put togeather.
Sounds simple but like I said I've always been bad at wireing trailer lights and have blown afew fuses.
THANKS

trailer wiring:
First thing you need to do is find out what wire goes where. Use a 12 volt tester on the vehicle and a 12 volt power source on the trailer. You are going to have to either make an adapter to go from the 5 wire plug to the 4 wire plug or you could replace both of them with a new plug system.

Standard wiring is:
Green = right turn/brake light
Yellow = left turn/brake light
Brown = running lights
White = ground
I can't find anything with your color code. The only thing I can find about 5 wire trailers is they are usually equipped with surge brakes. Does this trailer have surge brakes? They say with a 5 wire system, the extra wire goes to the back-up lights of the tow vehicle. This 5th wire sends a signal to disengage the surge brake system so you can back up without the brakes on the the trailer locking up.
The only recommendation I have for you is to find a small battery charger. Hook the - to the trailer frame and start testing. One of the wires should be ground (the white one?) so when you touch this one, you should get a short. This should not hurt the battery charger though, since it has a circuit breaker in it that will reset. That's the great thing about it, you can figure it out without blowing fuses, and see what wires do what.

The 4 way & 5 way are right, but once you go to 6 or seven, red is used for Left turn and stop, yellow then becomes the AUX or Backup, and Black is the 12V primary charge line. I wonder when the chart was made, at the time that may have been what everyone was going by.

In all the 18 wheel trailers I have wired (and there have been a lot) and other trailers I have never seen a yellow wire used for anything other than Left turn (and stop on small trailers).
The 18-Wheelers did use red for stop lamps.

Sounds simple but like I said I've always been bad at wireing trailer lights and have blown afew fuses.
first off the brown and yellow brown are connected together in the plug and are both for the tail lights look at the tail light on the trailer and you will see that the yellow and yellow brown go to one tail light and the green and brown goto the other light and the white wire goes to the frame of the trailer. the tail lights are grounded to the frame of the trailer.
I hope this helps you.
