Contrary to what the Quadratec rep stated over the phone, these will plug right into a 2013 model. The rep stated that the only difference between the 13 & 14 model year was the factory fog plugs. HOWEVER they do indeed have the same fog light plug throughout all JK model years. So the anti flicker harness plugged right into the OE wiring and the Ridgidindustries dually fog lamps.
The issue is that they don't exactly stop the flicker. They do delay the intervals of flicker but they are much brighter flicker pulses.
So I used my basic knowledge of electronics & assumed the following: these are trying to mitigate flicker by utalizing a capacitor to store the PWM pulsed signals from the jeep lighting circuitry. The issue is that there isn't anywhere for that stored energy to go. One the LED fog lamp flashes on like a camera flash, depleting the stored energy in the capacitors. I thought these were "anti flicker harnesses?" The solution is to install a resistor of adequate value (about 680-1k ohm) between the positive & negative leads. This way the small amount of power stored in the capacitors has a place to go. The resistor should only consume .2-.28 watts at 14 volts. Enough to stop the flickering & make these work!
One star for the extra hassles of a not so plug-&-play system.
