This is a rear washer bottle found only in 85-6 Golfs/GTI's is fits in the passenger side rear quarter ahead of the tail light. I like to use them to move the dead weight of the fluid to the rear. Also good for turbo guys not wanting to wash with there meth mix use this for your washer and the front for the meth. All you need to do is swap in your pump run the 2 wires from the under hood connector to the rear tap in to the rear washer line to convert it to your front feed and voila your done.
