On the harness and wiper washer pump.....that wire is part of the donor wiper harness...so there is no need for the painless harness to have that circuit. If you have the donor wiper harness, the pink wire runs direct from the column stalk switches to the washer pump. You will have to create your own ground for the pump.

As for the 2 aluminum pieces, I think I used to know what those were for, but I have never used them....they end up going right in the alum recycling bin.
