Default Water-spray and collumn washer spray?

Has anyone hooked up a water spray kit to the collumn windshield washer spray?
The plug that goes into the factory pump only has 2 wires. Has to be pos & neg.
I have a quantum racing water-spray kit, and want to hook it up to the stock wiring for the washer spray.
The kit has a switch, but to me, there would be no better place for this than stock washer spray.
Has anyone tried this?
Sounds easy.

But when you hit your washer spray button, won't your windshield wipers come on? Most likely...

From what i've seen, most people just add the I/C spray button.

I have had a home made IC sprayer for about a year now and find it to be very valuable on "warm" days in Arizona (we only say hot here when it's over ~118). I have a Wagon so I was able to build the system for a mere $16.

My problem has always been an effective switch. I wanted the stock STI switch because the fit and finish is perfect with the dash, but you have to hold the button in to spray. The STI has a relay somewhere that sprays for a few seconds each time the button is depressed. So- I have been using a rocker switch, but have on occasion left it on and forgotten about it (even ran it dry once, ouch!). I wish there was a way A-ECU could automatically trigger the sprayer like the piggyback engine management systems.

That said, in the spirit of many constituents on this board, I built an adjustable timing circuit for about $15. I based it on the very common LM-555 timing chip. The stock STI switch ($30) acts as a trigger that starts the timer and opens a 12v relay. A green LED, on the empty panel next to the spray switch, lights while it is spraying and turns off after the cycle. The amount of time can be adjusted with a potentiometer on the board, I have mine set for 6 sec burst. The whole circuit fits in a 2x3x1" enclosure and sticks inside the dash with double stick tape.

I will be happy to provide anyone on this forum with the plans and parts list if they want to build one. I am also considering putting a few together and selling them on Ebay for any turbo car with a manual IC-spray and am looking for some feedback. Anyone else come up with a timer or auto-spray that will work with A-ECU? Thanks.

I have yet to build my DIY IC spray kit but its something I plan on doing before summer time but I'm considering adding a pressure switch to the kit so that when boost pressure hits a set limit it will then kick on the sprayer. This way you flip the switch to activate it and that's it. Only downside is that if you're sitting in traffic you can't spray it since you won't be hitting boost b/c you're just parked there, idling.

You can pick them up in preset limits off eBay for like 25$, IIRC. I figured I'd get like a 2psi switch so that its already spraying by the time I hit full boost.

The real dilemma I'm having is finding a bottle to fit behind the battery since I have a wagon and want to retain the rear and front wiper sprayers.

I just wanted to offer this suggestion up to people who don't want to have to push and hold a button to run the sprayer, so you can keep 2 hands on the wheel or one on the wheel, the other on the shifter.

I never thought of that.
Oh well, I guess I'll just use a switch.
