Hello, I have a 2015 ram 1500 that came with factory LED tail light/turn signal but incandescent reverse bulbs. I swapped out to a complete set of after market LED tail lights w/reverse leds now I get the left turn signal out and fast flash on the mirror light and the dash cluster but nothing is out. I have been told to ground the rear bulb out detect to fix this but why should I need to if I had factory LEDS to begin with? Also where is that green wire w/white stripe located?

Replacement LEDS
