So I installed a new aftermarket 3rd brake light and license plate light from poison spyder. It had 3 wire system with red, black, and green wire. After install when I put on right turn signal the 3rd brake light also starts blinking with the right turn signal. Does anyone know which wire is the problem wire and what is the correct wire to attach it to? I have 2007 JKU, my friend has 2012 and the wiring is different. Inspection coming up or else I wouldn't really care. Thanks!

 

Dud you figure this out? I'm about to do the same mod.
