My dealer sold me a new 2010 trailer to mate to my 2012 RTS. The red trailer ligts act as both stop and turn but the 4 amber lights do not function as the RTS does with amber turn signals. Is there a problem with mating the older trailer wiring and if so is there a fix for it? I beleive the upper ambers can be changed out with clear and by using a jumper kit will function as back-ups but I also beleive the lower ambers should function as turn flashers.
