Not sure why you posted this in Plumbing but I have moved it to Trucks and Trailers.

Take a look at the diagram on the left. Hopefully that will help.

Are you adding these lights in addition to lights already installed, what are they for?
Do you already have stop, turn, tail, license and side marker lights?

If you want to add a light that is constantly on you would have to take power off the brown wire.
The brown wire on a 4-pin connector is tail, side marker and license plate lights.

These are new lights no lights has ever been installed on this trailer.new wire and 2 new lights.The lights did not come with a ground wire they will be grounded to metal when mounted.So I have 2 wires from each light run to front of trailer.The pigtail has 4 wires with one being a ground wire which I wI'll not use.
So how do I wire the 4 wires from trailer lights to only 3 wires on pig tail being the white wire is the ground on pigtail So this leaves me with 3 wires on pig tail to wire to r wires coming from lights on trailer.Thanks for your help

You need all four connections. Connect the black wire to the trailer frame. The ball is not a good enough ground for the lights.

Trust me, save yourself hours of frustration and run a good ground wire from the lights to the frame and, like Pete said, a ground from the pig tail to the frame. They'll probably work fine for a few years then you will be chasing a ghost trying to figure out why your lights are obsessed.

Ok got everything wired up and everything worked fine. Took a load of trash off and after awhile I decided to see if everything was still ok but it wasn't. Now when I turn left blinker on both blinkers blink and same when I turn right blinker on but very weak blinking.The only thing I have not done yet is run the ground wire from each light.Thanks for your help.

What you are describing is a poor ground. Do as the guys said in that regard and you'll be good to go.

Probably be a good idea to double check the ground on your truck also.
