STI intercooler sprayer

Finally got ahold of a stock sprayer and button. Will be getting all the harnesses and such, but I haven't a clue HOW to install it in my 07TR. I am very suprised no one has a thread on it. (at least one I could find)

Anyone have an idea or direct me to someplace/someone who does ???

Update : 01/22/08 - Get this, SUBARU will not sell the wiring harness alone for the sprayer. BUT, what they will "offer" to sell you is the 700.00 - 800.00 entire car harness.....
So, looks like I will be ghetto wiring it myself. Just keeping peeps up to date.

Update : 3/1/08
Got the tubing and STI OEM nozzles installed (mind you I had to drill into the splitter) Looks pretty damn good if you ask me. Next issue is the wiring. I THINK I found the schematic on the STI switch 5 pin.

( 1 2 3 X)
( 4 _ _ 5)

1- Manual Trigger
2- Illumination
3- Ground
4- I have no idea
5- Illumination Ground

* I would imagine the 2 grounds can be common grounded (correct me if I'm wrong)

Now the 4 pin setup on the pump are easy (well, 3 of them)

red - power
black - ground
green - level indicator (used in the STI) I don't think the WRX has that indicator on the gauge readout ??? Hell w/it, I don't need it.
The other, I don't know.

Pump is wired :
coming soon (need help)
