On GM cars the easiest thing to do to wire the wipers is trace all the wires from the wiper motor back to the connector under the dash. This connector then goes to the steering column and up to the switch on the stalk. All the electronics for the wiper function are in the stalk switch. The delay, park and multiple speed functions are all there. The only thing you need to do to make it work is provide power to the yellow wire on on the connector that goes to the column. You will also need to ground the black wire. That is it nothing else is needed and the system will stand alone.
I removed the stalk switch from my column and mounted it on the dash and just have it sticking out where the radio used to be. I have all the functions of the normal wiper setup.
