I finally mastered the little tricks for removing the four separate connectors. Best I can see is that the interior couldn't look much newer. It would be great to know which areas apply to the dome/cargo lights. But also should the 'connections' for the electric spoiler be included. The M-B # for this pump is 1708000848.

I don't know if this is a big deal or not, (battery is disconnected) but I just got continuity on one of the female pins on the small black connector. I will say that the connectors appear to be clean, but feel a good blast of high quality contact cleaner might help.

Unless there are 'things I can do', other than use contact cleaner, I'm guessing this is as far as I can go.
