Check your plug first with a tester too make sure that you have running lights there than work to your trailer lights.

I agree.Also check your vehicle lights with and without the trailer connected.It could be a ground on the trailer or a ground at the tow rig.

Make sure the side markers are wired into the correct wire - it should be the brown one only.
