After testing the wiper delay this afternoon, here are my results:

Wiper toggled: One pass every 10 seconds

Wiper/wash pushed and held: Water is deployed and wiper passes every 10 seconds.

The wiper 10-second delay works great, but when you want to wash your rear window the water simply streams down the window and onto your bumper, 10 seconds later the wiper activates. I don't know if it would be possible to have varying speeds depending on which way the button was toggled, but that would be ideal. Ken any ideas?

BTW, I just wired to the fuse box to test, but where can I find a switched 12V source under there? It all looks like colorful spaghetti to me.
