I have a 2015 flrt freewheler. I'm also missing my left arm. I have been riding it since i bought it and swapped the clutch to the right hand side (simply hooked it into the front master cylnder and bleed it) I'm trying to add the left turn signal to the right side using a simple button that I've already added, but I cannot find information on a 4 pin connector or even the right coloring code. I have a red a red/white a black/white and a black and that's all that runs into the left control. I want to know witch wire I need to splice into and if I need to add power or ground it. thanks
