I have the industrial kit in my '12 with the stock charger. Just has conservative tuning but it still runs 10x better.

I have a 2012 F350 with full LEDs all around with no resistor, capacitor, or different flasher. They all work normally and have from day 1. I bought resistors to wire in just incase but ended up not needing them. Ended up sticking them in the GF's Yukon.
