The unit that holds the bulbs needs replacing
as well as the plug with the 6 brown wires.
The OEM wiring will have multiple colors, this
picture was taken after changing the old one with the multi-color wires to the new kit which contains all brown wires.
Simple step by step instructions came with my kit. I have no wiring experience. All you need is a cigarette lighter and a pair of wire cutters/crimpers available at a Walmart or auto parts store, that can cut, strip and crimp the connectors. The pliers are very inexpensive
