Trailer wiring help!
Hi,
I am having trouble getting my trailer lights to work properly. I am getting signals working correctly as well as headlights, but the brake lights don't work on the trailer plug. I bought a converter box and found the brake light wire to splice into and now it dings "lamp out" when I hit the brakes and it still doesn't work properly. In fact, now I actually do have a brake light out but the bulb is fine.
Please help if you can, thanks!

always start with the truck. Does your truck-side plug test properly when you hit the brake? If so, then check continuity in the trailer. I use one of those testers with a light in the handle to check the truck side, and a multimeter to check the trailer side. Most times there is a grounding problem but if you have a turn signal then that probably not for your case since turn and brake are the same. Take it a step at a time, first check the truck output.
