I have searched on this subject for a while and haven't found any clear answers. I just bought the altezza taillights for my 2000 Altima and want to make sure I install them correctly. What exactly is the best sealant to use, and exactly where is it applied? I also read on a post somewhere that on of the wires isn't long enough and has to be extended? What does this mean and how do you do it? Thanks in advance for any tips on this installation procedure.
