it has been a long time and i lost my harness and now finially found it and hooked up. using Curts instructions. i used a test light at the plug and it checks out except for the right turn signal, but when i hook up to the trailer nothing works. i tested the trailer with a lawn mower battery so the trailer is fine. the odd thing is the brake light and turn signal is on the same wire and if i tap it into it nothing works. this has been by far the most confusing wiring project. it should be straight forward but i am getting all kinds of different results. This is very fustrating
