Wind shield wiper control

Someone on here gave me the glorious idea to re direct my windshield sprayers out the grill so i did with a little nozzle.

I was wondering if its possible to make the sprayer go on with out the wipers going

also if anyone else has done the sprayer out the grill what did you use for the nozzle head?

 

I knew someone that spun there nozzles 180 degrees on a lifted Chevy Blazer (old school full size one). He was high enough that he could shoot right onto the roof of the car in front of him. Was quite humorous. Sure you can wire it so the motor comes on only. It's just a matter of wiring it. They're two separate motors.

 

do you know where i could find out how to wire it?
