I know for sure the black off the light
Black = white on trailer check! ground works
The Red and Green I am not so sure.
I have a 4 pin harness. On the trailer itself there are 2 lights
at the back.
The one light
seems to do the brake, light and turn. The other which only has 1 wire to it seems to just make the light brighter. Whenever I plug this in i can get it lighter but still no brake light?
What can I do? Anythoughts on why the brake just cuts the light out?
Does it make a difference that I am only working on 1 side of the trailer? Should I pull both lights
and do them at the same time?
I have a similar yet opposite issue. I'm replacing my old lights with the new LED's that are from Princess Auto.
I used a light tester to test each connection at the light fixture side and I'm getting power to both Tail and brake/signal wires.
However, when everything is hooked up with the LED lights
installed my tail lights(running lights don't work) but signals and brakes
work. In addition my marker lights work when the headlights are on. The marker lights and tail lights
are hooked up on the same power.
I'm puzzled? What could cause the tail light of the LED not to work, when I know there is power running to them and they are on the same circuit as the marker lights which work?
Is this a poor ground issue? If so, why would the marker lights work?
