It is a standard White-ground, yellow left turn/brake light, green right turn/break light, brown tail. The lights come on and the left and right turn work fine, however' when I step on the brakes the lights turn off. I have hooked it up according to the directionsl The truck that I am using is a Ford Ranger. Any ideas?

Get you one of those $4 testers that pugs into the trucks side of the flat 4 pin connector. It will tell you if for sure if it's the truck or the trailer side. They sell them at marine stores, or walmart if you must. Rangers are particular about what year wiren harness you put on them. For instance a king cab vs a standard cab in the same year won't work. I think you've got the trailer hooked up just fine. Mine did that once and I took a jumper wire from the trailer to the frame under the bumper and the damn thing started working again. Just some more Ideas for ya. By the way, white is ground.

You have a bad ground. Does the white wire go to the lights or to the trailer frame? Try moving it or connect to the lights themselves. Is the plug on your truck ground good or are you using the trailer ball? The truck plug need a good ground also.

Your wiring colors are correct.

sounds like white running lights and brown ground. Un hook the four wire plug and using a test light see for sure ground the light on the bumper turn on parking lights see tail light color. push the brakes yellow and green right? Then hook the test light to either white and brown and see if you have them all. Note trailers are birds nests of black tape twisted shorting wires and corroded bulb sockets

Sounds like a ground. Have you got the trailer hooked up to the truck hitch? That is a ground when you are attached.

are your turn signals on the truck seperate from the brake lights ???

your hitch ball ISNT the ground and you should have the ground properly hooked up

I think your problem is with the white and green. Green should be ground not white.
