I basically followed this thread. STi intercooler sprayer
Thankyou BIG SKY WRX.
I have a couple tips on this install. Below u will see three pics. The blu crimp is what i used to wire the switch. Although two big, If u bend it together u can actually use these. Just get creative with the pliars. Another pic you will see is the pump i used. simple universal pump frrom pep boys. worked well. And the other pic u see is the wiper fluid hose. Be careful u get the right size. This is the size i had to use. Follow the link above and its a snap. Hope this helps out alittle. ANy questions feel free to pm me....frank
