Bought some LED switchback signals, back up lights, and brake lights. I also also got the led relay. But even with the relay swapped out they don't work. The passenger side signals fine, the drivers side will just come on and stay on. Brake lights don't come on, and the backup lights only seem to work when they feel like it. Anyone else run into this issue? Put it back to stock for now and it works fine, so it's not the truck.

Ground or connection issue?

try turning the bulb around 180 degrees. They have to be put in a certain way for everything to work properly. I had the same problem with my truck.

Sometimes the pins on the bulbs need to be bent the opposite way that they are now.
