Hello,

I bought one of these with all of the hardware to install (or at least I think I do...) But I have not installed it because the washer tank is so yellow. I have tried to bleach it out a few times and it helped. But its still pretty yellow. Does anyone know how to get the aged yellow color out of the plastic?

Also, does anyone have a step by step process on installing? Like where do the wires come through the firewall? Where does it connect to the fuse box? The exact location of the indicator under the dash? Or anything else you can think of. Its hard to find any info on-line on these things. My car did come with one of these from the factory so it should be a little bit easier to install. Thanks for the help!
