Maybe this will help:

The water spray system is not operational from the factory, the regulations said the parts had to be there, not necessarily work! There are three small plastic nozzles mounted on the rear of the steel bumper facing the intercooler radiator. On the bottom of the windscreen washer bottle there is a small (500 ml or so) chamber with a pump attached. Given the 10 gauge wiring and general size this is a very powerful pump. Pity it isn't actually wired to anything!

There is also some type of pneumatic pressure regulator fitted to the water bottle. An expensive wee doodah by the look of it, but as this area was smashed apart in the crash I never figured out how it connected. From it one vacuum line went to the cold start injector fuel line fitting (note CS injector isn't actually connected to fuel rail) and the other splices into the vacuum lines on the back of the block. Since I couldn't figure it out, I binned it! There is a also a distribution valve which merges the water pipes from the IC pump and the headlight sprayer pump and selects whether the water goes to the IC sprayers or headlight washers. Again, I couldn't figure this out so I turfed it. Now the IC pump is connected to the IC sprayers, and the headlight pump is connected to the headlight sprayers. A lot simpler? I reckon.

The small cavity on the bottom of the washer tank isn't actually connected to anything. There is a barbed fitting for a hose and a couple of smaller fittings for pipes. I was going to drill through so washer fluid drains down but then I realised that the barbed fitting is intended to take a hose from a larger water tank (inside the car) specifically intended for the IC spray. The smaller fittings may be for breathers of return lines. I intend to get an interior tank with a small feeder pump that can be filled as required.

Wiring is also required. I ran a 10 gauge wire from the fusebox via a relay and fuse. A small wire heads inside so that a small voltage only is required to activate the system. I have yet to decide how this will be done, but refer to the water spray articles at http://www.autospeed.com/A_0527/page1.html.
