You might try a capacitor harness to smooth out the power. I didn't need on on my '09 but ended up using one with the same bulbs and ballasts on my '11.I installed a set of Morimoto Mini H1 projectors with 35w bulbs and ballasts. After I connected everything the lights did not work. I eventually discovered that the wires in the factory harness must be backwards at the plug to the low beam bulb. So I switched them up and that got the HIDs working. Then when I went to start the truck they started flickering. So they work fine with the engine off. I do have some CAN BUS relays installed. The HIDs and relays are from theretrofitsource dot com. And all are Morimoto brand.
Could I have fried the relays by hooking up the relays in reversed polarity?
