Wiper Delay for 68 Barracuda

I've been driving it around a bit, and man would it be nice to have intermittent wipers here in the Great Northwest. I'm going to experiment soon with this module:

This module allows for an adjustable pulse so my plan is to adjust the pulse length just long enough to get the wiper arms to move past the park function, and then they will automatically return to the parked position. If this works I'm going to be so happy. I just wish I could install the controls on the turn signal stalk. Something is better than nothing I suppose.
