I'm trying to figure out what kit to get and from whom for my truck, doing lows and fogs.
For true plug and pray there are two ways to get there....
1. Is get "Canbus" ballasts. These are wired specifically to handle the feedback loop that gives you flickering.
2. Get anti-flicker modules if using standard ballasts.
Either method will work. If you are running 55 watt bulbs and ballasts I still recommend going with a separate wiring harness and doing it through relays with the battery being the main power source.
