Trailer lights no worky

[Copasetic]

I have a set of trailer lights on the back of a hitch mounted rack to drop the height of my tail lights. When I hooked them up they didn't work. I hooked my trailer up to the pigtail and they still didn't work. I bought a new pigtail, installed it, made sure I had a good ground, and STILL didn't work. any ideas? My tail lights (brake, stop, turn, running lights) all work like they should. I'm stumped.

So none of the trailer lights work?? No signals or running lights?? Then both left and right signal wires and the running light wire are broken/not making a conection or you still dont have a good ground. How did you test your ground ?? Have you checked the plug on your truck with a test light ??

No. No test light. Looks like another trip to Harbor Freight tomorrow! I wire brushed a spot on the frame, drilled a pilot hole and screwed the ground wire with a terminal to it and paitned it so it wouldn't rust. I figured that was a good ground, lol. I traced the wires as far back as I could and everything looks like it's in good shape. I didn't notice it till I had my bumpers put on a while back. Everything else is fine though so I don't know what gives.

That should be a good ground but odds are its still a ground problem. I fthe ground is good ALL 3 of the other wires have to be bad or both elements in both bulbs are burnt out or both bulbs arnt making a good conection in the bulbholder.

Actually with a bad ground you still will get eratic light on turn signal, I can't tell you what the problem is, the best thing is to test the wiring all the way.
Maybe you have a short in the wiring

Problem solved! I got to tracing the wires under the truck and then that's when it hit me. I looked again at where the pigtail was connected and I saw it. When my buddy took my rear bumper off he unplugged the pigtail where it connects into the harness. when he plugged it back in he put the pigtial in the wrong plug. I unplugged it and connected it into the only other plug that matched and "WOO HOO!" I have trailer lights again!! Thanks guys!

I knew it couldn't be the ground
It happens to the best of them
