After the 3rd tail light replacement, I could not purchase the socket that plugs into the assembly, I had to buy the plug, it comes bare, no pins or wires, the pins are sold one at a time the wire color is brown, so I needed to replace one of mine so I copied the color codes then snipped each one off , then after i inserted the lamp assembly, I bought some dilectric grease, thats what was never placed into ever plug that has movement with vibrations all the time, and when is shorts out the pin then you are left with no plug for a lamp to work its only a matter of time before that happens so apply a great amount of the grease into the plug and be sure that all pins are all in good condition!! and then it should be your last time you buy an expensive tail light !!! Good Luck and still asking for my rear wiper fix, my rear wiper works but cant be shut off, is there a relay some where for that rear wiper ?????
