The silverados are fortunate to be able to install the frx projectors. It's trial n error and you gotta have patience. Now that is just for the projectors...with the ddm kits and morimoto kit, you gotta be persistent when problems arises..im a newbie with the hids but it comes down to the connection to battery, ground, connections to each other, ballasts touching the bulbs, and ecms. I done so much reading from other hid sites that r available. No matter how you look at it motomedic is right on the money. Gotta order 2 kits for ddm...morimotos has its own troubles. They r all made overseas at a discounted $
